Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

In commit 9669f51de5 I tried to get rid of the undocumented cow gc
lifetime knob. The knob's function was never documented and it now
doesn't really have a function since eof and cow gc have been
consolidated.
Regrettably, xfs/231 relies on it and regresses on for-next. I did not
succeed at getting far enough through fstests patch review for the fixup
to land in time.
Restore the sysctl knob, document what it did (does?), put it on the
deprecation schedule, and rip out a redundant function.

Here is the "big" driver core and debugfs update for 5.12-rc1
This set of driver core patches caused a bunch of problems in linux-next
for the past few weeks, when Saravana tried to set fw_devlink=on as the
default functionality. This caused a number of systems to stop booting,
and lots of bugs were fixed in this area for almost all of the reported
systems, but this option is not ready to be turned on just yet for the
default operation based on this testing, so I've reverted that change at
the very end so we don't have to worry about regressions in 5.12. We
will try to turn this on for 5.13 if testing goes better over the next
few months.
Other than the fixes caused by the fw_devlink testing in here, there's
not much more:
- debugfs fixes for invalid input into debugfs_lookup()
- kerneldoc cleanups
- warn message if platform drivers return an error on their
remove callback (a futile effort, but good to catch).
All of these have been in linux-next for a while now, and the
regressions have gone away with the revert of the fw_devlink change.

Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
Compute Express Link which released the 2.0 specification in November.
The Linux relevant changes in CXL 2.0 are support for an OS to
dynamically assign address space to memory devices, support for
switches, persistent memory, and hotplug. A Type-3 Memory Device is a
PCI enumerated device presenting the CXL Memory Device Class Code and
implementing the CXL.mem protocol. CXL.mem allows device to advertise
CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
"Persistent Memory" in Linux /proc/iomem terms.
In addition to the CXL.mem fast path there is an administrative command
hardware mailbox interface for maintenance and provisioning. It is this
command interface that is the focus of the initial driver. With this
driver a CXL device that is mapped by the BIOS can be administered by
Linux. Linux support for CXL PMEM and dynamic CXL address space
management are to be implemented post v5.12.

Pull initial support for CXL (Compute Express Link) from Dan Williams:
"Introduce an initial driver for CXL 2.0 Type-3 Memory Devices.
CXL is Compute Express Link which released the 2.0 specification in
November. The Linux relevant changes in CXL 2.0 are support for an OS
to dynamically assign address space to memory devices, support for
switches, persistent memory, and hotplug.
A Type-3 Memory Device is a PCI enumerated device presenting the CXL
Memory Device Class Code and implementing the CXL.mem protocol.
CXL.mem allows device to advertise CPU and I/O coherent memory to the
system, i.e. typical "System RAM" and "Persistent Memory" in Linux
/proc/iomem terms.
In addition to the CXL.mem fast path there is an administrative
command hardware mailbox interface for maintenance and provisioning.
It is this command interface that is the focus of the initial driver.
With this driver a CXL device that is mapped by the BIOS can be
administered by Linux.
Linux support for CXL PMEM and dynamic CXL address space management
are to be implemented post v5.12"

"Here's a set of minor keyrings fixes/cleanups that I've collected from
various people for the upcoming merge window.
A couple of them might, in theory, be visible to userspace:
- Make blacklist_vet_description() reject uppercase letters as they
don't match the all-lowercase hex string generated for a blacklist
search.
This may want reconsideration in the future, but, currently, you
can't add to the blacklist keyring from userspace and the only
source of blacklist keys generates lowercase descriptions.
- Fix blacklist_init() to use a new KEY_ALLOC_* flag to indicate that
it wants KEY_FLAG_KEEP to be set rather than passing KEY_FLAG_KEEP
into keyring_alloc() as KEY_FLAG_KEEP isn't a valid alloc flag.
This isn't currently a problem as the blacklist keyring isn't
currently writable by userspace.
The rest of the patches are cleanups and I don't think they should
have any visible effect"

Merge tag 'idmapped-mounts-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull idmapped mounts from Christian Brauner:
"This introduces idmapped mounts which has been in the making for some
time. Simply put, different mounts can expose the same file or
directory with different ownership. This initial implementation comes
with ports for fat, ext4 and with Christoph's port for xfs with more
filesystems being actively worked on by independent people and
maintainers.
Idmapping mounts handle a wide range of long standing use-cases. Here
are just a few:
- Idmapped mounts make it possible to easily share files between
multiple users or multiple machines especially in complex
scenarios. For example, idmapped mounts will be used in the
implementation of portable home directories in
systemd-homed.service(8) where they allow users to move their home
directory to an external storage device and use it on multiple
computers where they are assigned different uids and gids. This
effectively makes it possible to assign random uids and gids at
login time.
- It is possible to share files from the host with unprivileged
containers without having to change ownership permanently through
chown(2).
- It is possible to idmap a container's rootfs and without having to
mangle every file. For example, Chromebooks use it to share the
user's Download folder with their unprivileged containers in their
Linux subsystem.
- It is possible to share files between containers with
non-overlapping idmappings.
- Filesystem that lack a proper concept of ownership such as fat can
use idmapped mounts to implement discretionary access (DAC)
permission checking.
- They allow users to efficiently changing ownership on a per-mount
basis without having to (recursively) chown(2) all files. In
contrast to chown (2) changing ownership of large sets of files is
instantenous with idmapped mounts. This is especially useful when
ownership of a whole root filesystem of a virtual machine or
container is changed. With idmapped mounts a single syscall
mount_setattr syscall will be sufficient to change the ownership of
all files.
- Idmapped mounts always take the current ownership into account as
idmappings specify what a given uid or gid is supposed to be mapped
to. This contrasts with the chown(2) syscall which cannot by itself
take the current ownership of the files it changes into account. It
simply changes the ownership to the specified uid and gid. This is
especially problematic when recursively chown(2)ing a large set of
files which is commong with the aforementioned portable home
directory and container and vm scenario.
- Idmapped mounts allow to change ownership locally, restricting it
to specific mounts, and temporarily as the ownership changes only
apply as long as the mount exists.
Several userspace projects have either already put up patches and
pull-requests for this feature or will do so should you decide to pull
this:
- systemd: In a wide variety of scenarios but especially right away
in their implementation of portable home directories.
https://systemd.io/HOME_DIRECTORY/
- container runtimes: containerd, runC, LXD:To share data between
host and unprivileged containers, unprivileged and privileged
containers, etc. The pull request for idmapped mounts support in
containerd, the default Kubernetes runtime is already up for quite
a while now: https://github.com/containerd/containerd/pull/4734
- The virtio-fs developers and several users have expressed interest
in using this feature with virtual machines once virtio-fs is
ported.
- ChromeOS: Sharing host-directories with unprivileged containers.
I've tightly synced with all those projects and all of those listed
here have also expressed their need/desire for this feature on the
mailing list. For more info on how people use this there's a bunch of
talks about this too. Here's just two recent ones:
https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdfhttps://fosdem.org/2021/schedule/event/containers_idmap/
This comes with an extensive xfstests suite covering both ext4 and
xfs:
https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts
It covers truncation, creation, opening, xattrs, vfscaps, setid
execution, setgid inheritance and more both with idmapped and
non-idmapped mounts. It already helped to discover an unrelated xfs
setgid inheritance bug which has since been fixed in mainline. It will
be sent for inclusion with the xfstests project should you decide to
merge this.
In order to support per-mount idmappings vfsmounts are marked with
user namespaces. The idmapping of the user namespace will be used to
map the ids of vfs objects when they are accessed through that mount.
By default all vfsmounts are marked with the initial user namespace.
The initial user namespace is used to indicate that a mount is not
idmapped. All operations behave as before and this is verified in the
testsuite.
Based on prior discussions we want to attach the whole user namespace
and not just a dedicated idmapping struct. This allows us to reuse all
the helpers that already exist for dealing with idmappings instead of
introducing a whole new range of helpers. In addition, if we decide in
the future that we are confident enough to enable unprivileged users
to setup idmapped mounts the permission checking can take into account
whether the caller is privileged in the user namespace the mount is
currently marked with.
The user namespace the mount will be marked with can be specified by
passing a file descriptor refering to the user namespace as an
argument to the new mount_setattr() syscall together with the new
MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
of extensibility.
The following conditions must be met in order to create an idmapped
mount:
- The caller must currently have the CAP_SYS_ADMIN capability in the
user namespace the underlying filesystem has been mounted in.
- The underlying filesystem must support idmapped mounts.
- The mount must not already be idmapped. This also implies that the
idmapping of a mount cannot be altered once it has been idmapped.
- The mount must be a detached/anonymous mount, i.e. it must have
been created by calling open_tree() with the OPEN_TREE_CLONE flag
and it must not already have been visible in the filesystem.
The last two points guarantee easier semantics for userspace and the
kernel and make the implementation significantly simpler.
By default vfsmounts are marked with the initial user namespace and no
behavioral or performance changes are observed.
The manpage with a detailed description can be found here:
1d7b902e28
In order to support idmapped mounts, filesystems need to be changed
and mark themselves with the FS_ALLOW_IDMAP flag in fs_flags. The
patches to convert individual filesystem are not very large or
complicated overall as can be seen from the included fat, ext4, and
xfs ports. Patches for other filesystems are actively worked on and
will be sent out separately. The xfstestsuite can be used to verify
that port has been done correctly.
The mount_setattr() syscall is motivated independent of the idmapped
mounts patches and it's been around since July 2019. One of the most
valuable features of the new mount api is the ability to perform
mounts based on file descriptors only.
Together with the lookup restrictions available in the openat2()
RESOLVE_* flag namespace which we added in v5.6 this is the first time
we are close to hardened and race-free (e.g. symlinks) mounting and
path resolution.
While userspace has started porting to the new mount api to mount
proper filesystems and create new bind-mounts it is currently not
possible to change mount options of an already existing bind mount in
the new mount api since the mount_setattr() syscall is missing.
With the addition of the mount_setattr() syscall we remove this last
restriction and userspace can now fully port to the new mount api,
covering every use-case the old mount api could. We also add the
crucial ability to recursively change mount options for a whole mount
tree, both removing and adding mount options at the same time. This
syscall has been requested multiple times by various people and
projects.
There is a simple tool available at
https://github.com/brauner/mount-idmapped
that allows to create idmapped mounts so people can play with this
patch series. I'll add support for the regular mount binary should you
decide to pull this in the following weeks:

The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".
Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the function key code and do the conversion
whenever necessary.
Since the userpace already knows the key scanlines (row/column)
associated with a received key code. Essentially, the userspace only
needs a mapping between the key row/column and the matching physical
location in the top row.
So, enhance the cros-ec-keyb driver to create such a mapping
and expose it to userspace in the form of a function_row_physmap

You should use KCFLAGS to pass additional compiler flags from the
command line. Using EXTRA_CFLAGS is wrong.
EXTRA_CFLAGS is supposed to specify flags applied only to the current
Makefile (and now deprecated in favor of ccflags-y).
It is still used in arch/mips/kvm/Makefile (and possibly in external
modules too). Passing EXTRA_CFLAGS from the command line overwrites
it and breaks the build.
I also fixed drivers/gpu/drm/tilcdc/Makefile because commit 816175dd1f
("drivers/gpu/drm/tilcdc: Makefile, only -Werror when no -W* in
EXTRA_CFLAGS") was based on the same misunderstanding.

Pull documentation updates from Jonathan Corbet:
"It has been a relatively quiet cycle in docsland.
- As promised, the minimum Sphinx version to build the docs is now
1.7, and we have dropped support for Python 2 entirely. That
allowed the removal of a bunch of compatibility code.
- A set of treewide warning fixups from Mauro that I applied after it
became clear nobody else was going to deal with them.
- The automarkup mechanism can now create cross-references from
relative paths to RST files.
- More translations, typo fixes, and warning fixes"

clk drivers that dominate the diffstat because we add support for six SoCs from
that particular vendor. The other big change is the removal of various clk
drivers that are no longer used now that the kernel is dropping support for
those SoCs. Beyond that there's the usual non-critical fixes for existing
drivers and a good number of patches from Lee Jones that cleanup a bunch of W=1
enabled builds.
Removed Drivers:
- Remove efm32 clk driver
- Remove tango4 clk driver
- Remove zte zx clk driver
- Remove sirf prima2/atlast clk drivers
- Remove u300 clk driver

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"This is all driver updates, the majority of which is a bunch of new
Qualcomm clk drivers that dominate the diffstat because we add support
for six SoCs from that particular vendor.
The other big change is the removal of various clk drivers that are no
longer used now that the kernel is dropping support for those SoCs.
Beyond that there's the usual non-critical fixes for existing drivers
and a good number of patches from Lee Jones that cleanup a bunch of
W=1 enabled builds.
Removed Drivers:
- Remove efm32 clk driver
- Remove tango4 clk driver
- Remove zte zx clk driver
- Remove sirf prima2/atlast clk drivers
- Remove u300 clk driver
New Drivers:
- PLL support on MStar/SigmaStar ARMv7 SoCs
- CPU clks for Qualcomm SDX55
- GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs
- GCC clks for Qualcomm SM8350
- GPU clks for Qualcomm SDM660/SDM630
Updates:
- Video clk fixups on Qualcomm SM8250
- Improvements for multimedia clks on Qualcomm MSM8998
- Fix many warnings with W=1 enabled builds under drivers/clk/
- Support crystal load capacitance for Versaclock VC5
- Add a "skip recall" DT binding for Silicon Labs' si570 to avoid
glitches at boot
- Convert Xilinx VCU clk driver to a proper clk provider driver
- Expose Xilinx ZynqMP clk driver to more platforms
- Amlogic pll driver fixup
- Amlogic meson8b clock controller dt support clean up
- Remove mipi clk from the Amlogic axg clock controller
- New Rockchip rk3368 clock ids related to camera input
- Use pr_notice() instead of pr_warn() on i.MX6Q pre-boot ldb_di_clk
reparenting
- A series from Liu Ying that adds some SCU clocks support for
i.MX8qxp DC0/MIPI-LVDS subsystems
- A series from Lucas Stach that adds PLL monitor clocks for i.MX8MQ,
and clkout1/2 support for i.MX8MM/MN
- Add I2c and Ethernet (RAVB) clocks on Renesas R-Car V3U
- Add timer (TMU) clocks on most Renesas R-Car Gen3 SoCs
- Add video-related (FCPVD/VSPD/VSPX), watchdog (RWDT), serial
(HSCIF), pincontrol/GPIO (PFC/GPIO), SPI (MSIOF), SDHI, and DMA
(SYS-DMAC) clocks on Renesas R-Car V3U
- Add support for the USB 2.0 clock selector on Renesas RZ/G2 SoCs
- Allwinner H616 SoC clk support"

The main focus of this release from a framework point of view has been
spi-mem where we've acquired support for a few new hardware features
which enable better performance on suitable hardware. Otherwise mostly
thanks to Arnd's cleanup efforts on old platforms we've removed several
obsolete drivers which just about balance out the newer drivers we've
added this cycle.
- Allow drivers to flag if they are unidirectional.
- Support for DTR mode and hardware acceleration of dummy cycles in spi-mem.
- Support for Allwinder H616, Intel Lightning Mountain, nVidia Tegra
QuadSPI, Realtek RTL838x and RTL839x.
- Removal of obsolute EFM32, Txx9 and SIRF Prima and Atlas drivers.

Pull i2c updates from Wolfram Sang:
- mostly driver updates. Bigger ones for mlxcpld and iproc. But most of
them are all over the place.
- removal of the efm32, sirf, u300, and zte zx bus drivers because of
platform removal. So, we have a pleasant diffstat this time.
- first set of cleanups in the I2C core as preparation to increase
maximum length of SMBus transfers to 255 (as specified in the new
standard). Better documentation of struct i2c_msg and its flags stand
out here.
- the testunit can now respond to SMBus block process calls which is
the testcase when implementing the above new maximum length.

A relatively calm release at this time, and no massive code changes
are found in the stats, while a wide range of code refactoring and
cleanup have been done.
Note that this update includes the tree-wide trivial changes for
dropping the return value from ISA remove callbacks, too.

* ALSA Core:
- Support for the software jack injection via debugfs

- Support for userspace to emulate Xen hypercalls
- Raise the maximum number of user memslots
- Scalability improvements for the new MMU. Instead of the complex
"fast page fault" logic that is used in mmu.c, tdp_mmu.c uses an
rwlock so that page faults are concurrent, but the code that can run
against page faults is limited. Right now only page faults take the
lock for reading; in the future this will be extended to some
cases of page table destruction. I hope to switch the default MMU
around 5.12-rc3 (some testing was delayed due to Chinese New Year).
- Cleanups for MAXPHYADDR checks
- Use static calls for vendor-specific callbacks
- On AMD, use VMLOAD/VMSAVE to save and restore host state
- Stop using deprecated jump label APIs
- Workaround for AMD erratum that made nested virtualization unreliable
- Support for LBR emulation in the guest
- Support for communicating bus lock vmexits to userspace
- Add support for SEV attestation command
- Miscellaneous cleanups
PPC:
- Support for second data watchpoint on POWER10
- Remove some complex workarounds for buggy early versions of POWER9
- Guest entry/exit fixes
ARM64
- Make the nVHE EL2 object relocatable
- Cleanups for concurrent translation faults hitting the same page
- Support for the standard TRNG hypervisor call
- A bunch of small PMU/Debug fixes
- Simplification of the early init hypercall handling
Non-KVM changes (with acks):
- Detection of contended rwlocks (implemented only for qrwlocks,
because KVM only needs it for x86)
- Allow __DISABLE_EXPORTS from assembly code
- Provide a saner follow_pfn replacements for modules

it's a same-content tree of 82891be90f3c (-next published)
merged with v5.11.
The main reason for the rebase was an authorship misattribution
problem with a new commit, which we noticed in the last minute,
and which we didn't want to be merged upstream. The offending
commit was deep in the tree, and dependent commits had to be
rebased as well. ]
- Core scheduler updates:
- Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
preempt=none/voluntary/full boot options (default: full),
to allow distros to build a PREEMPT kernel but fall back to
close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling
behavior via a boot time selection.
There's also the /debug/sched_debug switch to do this runtime.
This feature is implemented via runtime patching (a new variant of static calls).
The scope of the runtime patching can be best reviewed by looking
at the sched_dynamic_update() function in kernel/sched/core.c.
( Note that the dynamic none/voluntary mode isn't 100% identical,
for example preempt-RCU is available in all cases, plus the
preempt count is maintained in all models, which has runtime
overhead even with the code patching. )
The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast majority
of distributions, are supposed to be unaffected.
- Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
was found via rcutorture triggering a hang. The bug is that
rcu_idle_enter() may wake up a NOCB kthread, but this happens after
the last generic need_resched() check. Some cpuidle drivers fix it
by chance but many others don't.
In true 2020 fashion the original bug fix has grown into a 5-patch
scheduler/RCU fix series plus another 16 RCU patches to address
the underlying issue of missed preemption events. These are the
initial fixes that should fix current incarnations of the bug.
- Clean up rbtree usage in the scheduler, by providing & using the following
consistent set of rbtree APIs:
partial-order; less() based:
- rb_add(): add a new entry to the rbtree
- rb_add_cached(): like rb_add(), but for a rb_root_cached
total-order; cmp() based:
- rb_find(): find an entry in an rbtree
- rb_find_add(): find an entry, and add if not found
- rb_find_first(): find the first (leftmost) matching entry
- rb_next_match(): continue from rb_find_first()
- rb_for_each(): iterate a sub-tree using the previous two
- Improve the SMP/NUMA load-balancer: scan for an idle sibling in a single pass.
This is a 4-commit series where each commit improves one aspect of the idle
sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU utilization
metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by reducing the number
of active LB attempts & lengthen the load-balancing interval. This improves
stress-ng mmapfork performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can result in
too high utilization values
- Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()
- Clean up task priority related defines, remove *USER_*PRIO and
USER_PRIO()
- Simplify the sched_init_numa() deduplication sort
- Documentation updates
- Fix EAS bug in update_misfit_status(), which degraded the quality
of energy-balancing

Pull xfs updates from Darrick Wong:
"There's a lot going on this time, which seems about right for this
drama-filled year.
Community developers added some code to speed up freezing when
read-only workloads are still running, refactored the logging code,
added checks to prevent file extent counter overflow, reduced iolock
cycling to speed up fsync and gc scans, and started the slow march
towards supporting filesystem shrinking.
There's a huge refactoring of the internal speculative preallocation
garbage collection code which fixes a bunch of bugs, makes the gc
scheduling per-AG and hence multithreaded, and standardizes the retry
logic when we try to reserve space or quota, can't, and want to
trigger a gc scan. We also enable multithreaded quotacheck to reduce
mount times further. This is also preparation for background file gc,
which may or may not land for 5.13.
We also fixed some deadlocks in the rename code, fixed a quota
accounting leak when FSSETXATTR fails, restored the behavior that
write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
where sgid directory inheritance wasn't quite working properly, and
fixed a bug where symlinks weren't working properly in ecryptfs. We
also now advertise the inode btree counters feature that was
introduced two cycles ago.
Summary:
- Fix an ABBA deadlock when renaming files on overlayfs.
- Make sure that we can't overflow the inode extent counters when
adding to or removing extents from a file.
- Make directory sgid inheritance work the same way as all the other
filesystems.
- Don't drain the buffer cache on freeze and ro remount, which should
reduce the amount of time if read-only workloads are continuing
during the freeze.
- Fix a bug where symlink size isn't reported to the vfs in ecryptfs.

Add an ioctl which allows reading fs-verity metadata from a file.
This is useful when a file with fs-verity enabled needs to be served
somewhere, and the other end wants to do its own fs-verity compatible
verification of the file. See the commit messages for details.
This new ioctl has been tested using new xfstests I've written for it.

We've added two major features: 1) compression level and 2) checkpoint_merge, in
this round. 1) compression level expands 'compress_algorithm' mount option to
accept parameter as format of <algorithm>:<level>, by this way, it gives a way
to allow user to do more specified config on lz4 and zstd compression level,
then f2fs compression can provide higher compress ratio. 2) checkpoint_merge
creates a kernel daemon and makes it to merge concurrent checkpoint requests as
much as possible to eliminate redundant checkpoint issues. Plus, we can
eliminate the sluggish issue caused by slow checkpoint operation when the
checkpoint is done in a process context in a cgroup having low i/o budget and
cpu shares.
Enhancement:
- add compress level for lz4 and zstd in mount option
- checkpoint_merge mount option
- deprecate f2fs_trace_io
Bug fix:
- flush data when enabling checkpoint back
- handle corner cases of mount options
- missing ACL update and lock for I_LINKABLE flag
- attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
- fix potential deadlock in compression flow
- fix wrong submit_io condition
As usual, we've cleaned up many code flows and fixed minor bugs.

Merge tag 'f2fs-for-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"We've added two major features: 1) compression level and 2)
checkpoint_merge, in this round.
Compression level expands 'compress_algorithm' mount option to accept
parameter as format of <algorithm>:<level>, by this way, it gives a
way to allow user to do more specified config on lz4 and zstd
compression level, then f2fs compression can provide higher compress
ratio.
checkpoint_merge creates a kernel daemon and makes it to merge
concurrent checkpoint requests as much as possible to eliminate
redundant checkpoint issues. Plus, we can eliminate the sluggish issue
caused by slow checkpoint operation when the checkpoint is done in a
process context in a cgroup having low i/o budget and cpu shares.
Enhancements:
- add compress level for lz4 and zstd in mount option
- checkpoint_merge mount option
- deprecate f2fs_trace_io
Bug fixes:
- flush data when enabling checkpoint back
- handle corner cases of mount options
- missing ACL update and lock for I_LINKABLE flag
- attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
- fix potential deadlock in compression flow
- fix wrong submit_io condition
As usual, we've cleaned up many code flows and fixed minor bugs"

Here is the "big" set of staging and IIO driver patches for 5.12-rc1.
Nothing really huge in here, the number of staging tree patches has gone
down for a bit, maybe there's only so much churn to happen in here at
the moment.
The IIO changes are:
- new drivers
- new DT bindings
- new iio driver features
with full details in the shortlog.
The staging driver patches are just a lot of tiny coding style cleanups,
along with some semi-larger hikey driver cleanups as those are _almost_
good enough to get out of the staging tree, but will probably have to
wait until 5.13 to have happen.
All of these have been in linux-next with no reported issues.
