native Linux games can benefit from this interface as this is a common
wait pattern for this kind of applications.
- Add context to ww_mutex_trylock() to provide a path for i915 to rework
their eviction code step by step without making lockdep upset until the
final steps of rework are completed. It's also useful for regulator and
TTM to avoid dropping locks in the non contended path.

- A few improvements for the RT substitutions.

Pull btrfs updates from David Sterba:
"The updates this time are more under the hood and enhancing existing
features (subpage with compression and zoned namespaces).
Performance related:
- misc small inode logging improvements (+3% throughput, -11% latency
on sample dbench workload)
- more efficient directory logging: bulk item insertion, less tree
searches and locking
- speed up bulk insertion of items into a b-tree, which is used when
logging directories, when running delayed items for directories
(fsync and transaction commits) and when running the slow path
(full sync) of an fsync (bulk creation run time -4%, deletion -12%)
Core:
- continued subpage support
- make defragmentation work
- make compression write work
- zoned mode
- support ZNS (zoned namespaces), zone capacity is number of
usable blocks in each zone
- add dedicated block group (zoned) for relocation, to prevent
out of order writes in some cases
- greedy block group reclaim, pick the ones with least usable
space first
- preparatory work for send protocol updates
- error handling improvements
- cleanups and refactoring
Fixes:
- lockdep warnings
- in show_devname callback, on seeding device
- device delete on loop device due to conversions to workqueues
- fix deadlock between chunk allocation and chunk btree modifications
- fix tracking of missing device count and status"

Commit ccaa66c8dd reinstated the kmap/kunmap that had been dropped in
commit 8c945d32e6 ("btrfs: compression: drop kmap/kunmap from lzo").
However, it seems to have done so incorrectly due to the change not
reverting cleanly, and lzo_decompress_bio() ended up not having a
matching "kunmap()" to the "kmap()" that was put back.
Also, any assert that the page pointer is not NULL should be before the
kmap() of said pointer, since otherwise you'd just oops in the kmap()
before the assert would even trigger.
I noticed this when trying to verify my btrfs merge, and things not
adding up. I'm doing this fixup before re-doing my merge, because this
commit needs to also be backported to 5.15 (after verification from the
btrfs people).

In 1394 OHCI specification, Isochronous Receive DMA context has several
modes. One of mode is 'BufferFill' and Linux FireWire stack uses it to
receive isochronous packets for multiple isochronous channel as
FW_ISO_CONTEXT_RECEIVE_MULTICHANNEL.
The mode is not used by in-kernel driver, while it's available for
userspace. The character device driver in firewire-core includes
cast of function callback for the mode since the type of callback
function is different from the other modes. The case is inconvenient
to effort of Control Flow Integrity builds due to
-Wcast-function-type warning.
This commit removes the cast. A static helper function is newly added
to initialize isochronous context for the mode. The helper function
arranges isochronous context to assign specific callback function
after call of existent kernel API. It's noticeable that the number of
isochronous channel, speed, and the size of header are not required for
the mode. The helper function is used for the mode by character device
driver instead of direct call of existent kernel API.
The same goal can be achieved (in the ioctl_create_iso_context function)
without this helper function as follows:
- Call the fw_iso_context_create function passing NULL to the callback
parameter.
- Then setting the context->callback.sc or context->callback.mc
variables based on the a->type value.
However using the helper function created in this patch makes code more
clear and declarative. This way avoid the call to a function with one
purpose to achieved another one.

Pull erofs updates from Gao Xiang:
"There are some new features available for this cycle. Firstly, EROFS
LZMA algorithm support, specifically called MicroLZMA, is available as
an option for embedded devices, LiveCDs and/or as the secondary
auxiliary compression algorithm besides the primary algorithm in one
file.
In order to better support the LZMA fixed-sized output compression,
especially for 4KiB pcluster size (which has lowest memory pressure
thus useful for memory-sensitive scenarios), Lasse introduced a new
LZMA header/container format called MicroLZMA to minimize the original
LZMA1 header (for example, we don't need to waste 4-byte dictionary
size and another 8-byte uncompressed size, which can be calculated by
fs directly, for each pcluster) and enable EROFS fixed-sized output
compression.
Note that MicroLZMA can also be later used by other things in addition
to EROFS too where wasting minimal amount of space for headers is
important and it can be only compiled by enabling XZ_DEC_MICROLZMA.
MicroLZMA has been supported by the latest upstream XZ embedded [1] &
XZ utils [2], apply the latest related XZ embedded upstream patches by
the XZ author Lasse here.
Secondly, multiple device is also supported in this cycle, which is
designed for multi-layer container images. By working together with
inter-layer data deduplication and compression, we can achieve the
next high-performance container image solution. Our team will announce
the new Nydus container image service [3] implementation with new RAFS
v6 (EROFS-compatible) format in Open Source Summit 2021 China [4]
soon.
Besides, the secondary compression head support and readmore
decompression strategy are also included in this cycle. There are also
some minor bugfixes and cleanups, as always.
Summary:
- support multiple devices for multi-layer container images;
- support the secondary compression head;
- support readmore decompression strategy;
- support new LZMA algorithm (specifically called MicroLZMA);
- some bugfixes & cleanups"

struct ib_sge totally.
This can increase the rx performance of irdma.

This patch is closely related to commit 6016df8fe8 ("selftests/bpf:
Fix broken riscv build"). When clang includes the system include
directories, but targeting BPF program, __BITS_PER_LONG defaults to
32, unless explicitly set. Work around this problem, by explicitly
setting __BITS_PER_LONG to __riscv_xlen.

After "skmsg: lose offset info in sk_psock_skb_ingress", the test case
with ktls failed. This because ktls parser(tls_read_size) return value
is 285 not 256.
The case like this:
tls_sk1 --> redir_sk --> tls_sk2
tls_sk1 sent out 512 bytes data, after tls related processing redir_sk
recved 570 btyes data, and redirect 512 (skb_use_parser) bytes data to
tls_sk2; but tls_sk2 needs 285 * 2 bytes data, receive timeout occurred.

If sockmap enable strparser, there are lose offset info in
sk_psock_skb_ingress(). If the length determined by parse_msg function is not
skb->len, the skb will be converted to sk_msg multiple times, and userspace
app will get the data multiple times.
Fix this by get the offset and length from strp_msg. And as Cong suggested,
add one bit in skb->_sk_redir to distinguish enable or disable strparser.

Disabling unprivileged BPF would help prevent unprivileged users from
creating certain conditions required for potential speculative execution
side-channel attacks on unmitigated affected hardware.
A deep dive on such attacks and current mitigations is available here [0].
Sync with what many distros are currently applying already, and disable
unprivileged BPF by default. An admin can enable this at runtime, if
necessary, as described in 08389d8882 ("bpf: Add kconfig knob for

Pull memory folios from Matthew Wilcox:
"Add memory folios, a new type to represent either order-0 pages or the
head page of a compound page. This should be enough infrastructure to
support filesystems converting from pages to folios.
The point of all this churn is to allow filesystems and the page cache
to manage memory in larger chunks than PAGE_SIZE. The original plan
was to use compound pages like THP does, but I ran into problems with
some functions expecting only a head page while others expect the
precise page containing a particular byte.
The folio type allows a function to declare that it's expecting only a
head page. Almost incidentally, this allows us to remove various calls
to VM_BUG_ON(PageTail(page)) and compound_head().
This converts just parts of the core MM and the page cache. For 5.17,
we intend to convert various filesystems (XFS and AFS are ready; other
filesystems may make it) and also convert more of the MM and page
cache to folios. For 5.18, multi-page folios should be ready.
The multi-page folios offer some improvement to some workloads. The
80% win is real, but appears to be an artificial benchmark (postgres
startup, which isn't a serious workload). Real workloads (eg building
the kernel, running postgres in a steady state, etc) seem to benefit
between 0-10%. I haven't heard of any performance losses as a result
of this series. Nobody has done any serious performance tuning; I
imagine that tweaking the readahead algorithm could provide some more
interesting wins. There are also other places where we could choose to
create large folios and currently do not, such as writes that are
larger than PAGE_SIZE.
I'd like to thank all my reviewers who've offered review/ack tags:
Christoph Hellwig, David Howells, Jan Kara, Jeff Layton, Johannes
Weiner, Kirill A. Shutemov, Michal Hocko, Mike Rapoport, Vlastimil
Babka, William Kucharski, Yu Zhao and Zi Yan.

There are a lot of warnings due to unused protocol constants, but I believe
it's good to leave them in the sources for documentation purposes for further
development.
Switch them over from static conts to macros to avoid the warnings.

The driver requires multicolor LED support; express that in Kconfig.

Tracepoints for SMC
This patch set introduces tracepoints for SMC, including the tracepoints
basic code. The tracepoitns would help us to track SMC's behaviors by
automatic tools, or other BPF tools, and zero overhead if not enabled.
Compared with kprobe and other dymatic tools, the tracepoints are
considered as stable API, and less overhead for tracing with easy-to-use
API.

SMC-R link down event is important to help us find links' issues, we
should track this event, especially in the single nic mode, which means
upper layer connection would be shut down. Then find out the direct
link-down reason in time, not only increased the counter, also the
location of the code who triggered this event.

This introduce two tracepoints for smc tx and rx msg to help us
diagnosis issues of data path. These two tracepoitns don't cover the
path of CORK or MSG_MORE in tx, just the top half of data path.

This introduces tracepoint for smc fallback to TCP, so that we can track
which connection and why it fallbacks, and map the clcsocks' pointer with
/proc/net/tcp to find more details about TCP connections. Compared with
kprobe or other dynamic tracing, tracepoints are stable and easy to use.
