Dick Kennedy 2299e4323d scsi: lpfc: Fix warning messages when NVME_TARGET_FC not defined
Warning messages when NVME_TARGET_FC not defined on ppc builds

The lpfc_nvmet_replenish_context() function is only meaningful when NVME
target mode enabled. Surround the function body with ifdefs for target
mode enablement.

Dick Kennedy 2b75d0f934 scsi: lpfc: Fix lpfc nvme host rejecting IO with Not Ready message
In a link bounce scenario, a condition can occur where the discovery
engine swaps an ndlp structure (address change for an nport). While the
swap was successfully executed by the discovery engine, the driver did
not properly detect a change in the ndlp bound to the nvme rport.  This
error resulted in the nvme host transport issuing an IO to the correct
nvme rport, but the lpfc driver addressed a ndlp with an NLP_UNUSED
status and failed the io. This resulting it it looking like there were
missing namespaces and applications failed due to io errors.

To fix, in lpfc_nvme_register_rport, rework the "rebind" case to break
the nvme rport<->ndlp association when the ndlp already has an
nrport. Then rebind the rport to the correct ndlp data and backpointers.

[mkp: typo]

Dick Kennedy 1234a6d54f scsi: lpfc: Fix crash receiving ELS while detaching driver
The driver crashes when attempting to use a freed ndpl pointer.

The pci_remove_one handler runs on a separate kernel thread. The order
of the removal is starting by freeing all of the ndlps and then
disabling interrupts. In between these two events the driver can still
receive an ELS and process it. When it tries to use the ndlp pointer
will be NULL

Change the order of the pci_remove_one vs disable interrupts so that
interrupts are disabled before the ndlp's are freed.

Damien Le Moal b7af62a945 scsi: sd: Align maximum write same blocks to physical block size
Reporting a maximum number of blocks that is not aligned on the device
physical size would cause a large write same request to be split into
physically unaligned chunks by __blkdev_issue_write_zeroes() and
__blkdev_issue_write_same(), even if the caller of these functions took
care to align its request to physical sectors.

Make sure the maximum reported is aligned to the device physical block
size. This is only an optional optimization for regular disks, but this
is mandatory to avoid failure of large write same requests directed at
sequential write required zones of host-managed ZBC disks.

Another merge window, another MAINTAINERS file disaster.

People have serious problems with the alphabet and sorting, and poor
Jérôme Glisse and Radim Krčmář get their names mangled by locale issues,
turning them into some mangled mess (probably others do too, but those
two stood out when sorting things again).

And we now have two copies of the same 'AS3645A LED FLASH CONTROLLER
DRIVER' in the tree and in the MAINTAINERS file, but that's a separate
issue - the duplication is real, and I left them as two entries for the
same name.

This does not try to sort the actual section pattern entries, although I
may end up doing that later.

 "The diff is dominated by the Allwinner A10/A20 SoCs getting converted
  to the sunxi-ng framework. Otherwise, the heavy hitters are various
  drivers for SoCs like AT91, Amlogic, Renesas, and Rockchip. There are
  some other new clk drivers in here too but overall this is just a
  bunch of clk drivers for various different pieces of hardware and a
  collection of non-critical fixes for clk drivers.

  New Drivers:
   - Allwinner R40 SoCs
   - Renesas R-Car Gen3 USB 2.0 clock selector PHY
   - Atmel AT91 audio PLL
   - Uniphier PXs3 SoCs
   - ARC HSDK Board PLLs
   - AXS10X Board PLLs
   - STMicroelectronics STM32H743 SoCs

  Removed Drivers:
   - Non-compiling mb86s7x support

In this round, we've mostly tuned f2fs to provide better user experience
 for Android. Especially, we've worked on atomic write feature again with

 several facilities to analyze and enhance IO behaviors.
 
 Major changes include:
 - add app/fs io stat
 - add inode checksum feature
 - support project/journalled quota
 - enhance atomic write with new ioctl() which exposes feature set
 - enhance background gc/discard/fstrim flows with new gc_urgent mode
 - add F2FS_IOC_FS{GET,SET}XATTR

Richard Wareing b31ff3cdf5 xfs: XFS_IS_REALTIME_INODE() should be false if no rt device present
If using a kernel with CONFIG_XFS_RT=y and we set the RHINHERIT flag on
a directory in a filesystem that does not have a realtime device and
create a new file in that directory, it gets marked as a real time file.
When data is written and a fsync is issued, the filesystem attempts to
flush a non-existent rt device during the fsync process.

This results in a crash dereferencing a null buftarg pointer in
xfs_blkdev_issue_flush():

  BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
  IP: xfs_blkdev_issue_flush+0xd/0x20
  .....
  Call Trace:
    xfs_file_fsync+0x188/0x1c0
    vfs_fsync_range+0x3b/0xa0
    do_fsync+0x3d/0x70
    SyS_fsync+0x10/0x20
    do_syscall_64+0x4d/0xb0
    entry_SYSCALL64_slow_path+0x25/0x25

Setting RT inode flags does not require special privileges so any
unprivileged user can cause this oops to occur.  To reproduce, confirm
kernel is compiled with CONFIG_XFS_RT=y and run:

  # mkfs.xfs -f /dev/pmem0
  # mount /dev/pmem0 /mnt/test
  # mkdir /mnt/test/foo
  # xfs_io -c 'chattr +t' /mnt/test/foo
  # xfs_io -f -c 'pwrite 0 5m' -c fsync /mnt/test/foo/bar

Or just run xfstests with MKFS_OPTIONS="-d rtinherit=1" and wait.

Kernels built with CONFIG_XFS_RT=n are not exposed to this bug.
