Merge tag 'xfs-6.8-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Chandan Babu:
"New features/functionality:
- Online repair:
- Reserve disk space for online repairs
- Fix misinteraction between the AIL and btree bulkloader because
of which the bulk load fails to queue a buffer for writeback if
it happens to be on the AIL list
- Prevent transaction reservation overflows when reaping blocks
during online repair
- Whenever possible, bulkloader now copies multiple records into
a block
- Support repairing of
1. Per-AG free space, inode and refcount btrees
2. Ondisk inodes
3. File data and attribute fork mappings
- Verify the contents of
1. Inode and data fork of realtime bitmap file
2. Quota files
- Introduce MF_MEM_PRE_REMOVE. This will be used to notify tasks
about a pmem device being removed

Bug fixes:
- Fix memory leak of recovered attri intent items
- Fix UAF during log intent recovery
- Fix realtime geometry integer overflows
- Prevent scrub from live locking in xchk_iget
- Prevent fs shutdown when removing files during low free disk space
- Prevent transaction reservation overflow when extending an RT
device
- Prevent incorrect warning from being printed when extending a
filesystem
- Fix an off-by-one error in xreap_agextent_binval
- Serialize access to perag radix tree during deletion operation
- Fix perag memory leak during growfs
- Allow allocation of minlen realtime extent when the maximum sized
realtime free extent is minlen in size

Cleanups:
- Remove duplicate boilerplate code spread across functionality
associated with different log items
- Cleanup resblks interfaces
- Pass defer ops pointer to defer helpers instead of an enum
- Initialize di_crc in xfs_log_dinode to prevent KMSAN warnings
- Use static_assert() instead of BUILD_BUG_ON_MSG() to validate size
of structures and structure member offsets. This is done in order
to be able to share the code with userspace
- Move XFS documentation under a new directory specific to XFS
- Do not invoke deferred ops' ->create_done callback if the deferred
operation does not have an intent item associated with it
- Remove duplicate inclusion of header files from scrub/health.c
- Refactor Realtime code
- Cleanup attr code"

mm, pmem, xfs: Introduce MF_MEM_PRE_REMOVE for unbind

Now, if we suddenly remove a PMEM device(by calling unbind) which
contains FSDAX while programs are still accessing data in this device,
e.g.:
```
$FSSTRESS_PROG -d $SCRATCH_MNT -n 99999 -p 4 &
# $FSX_PROG -N 1000000 -o 8192 -l 500000 $SCRATCH_MNT/t001 &
echo "pfn1.1" > /sys/bus/nd/drivers/nd_pmem/unbind
```
it could come into an unacceptable state:
1. device has gone but mount point still exists, and umount will fail
with "target is busy"
2. programs will hang and cannot be killed
3. may crash with NULL pointer dereference

To fix this, we introduce a MF_MEM_PRE_REMOVE flag to let it know that we
are going to remove the whole device, and make sure all related processes
could be notified so that they could end up gracefully.

This patch is inspired by Dan's "mm, dax, pmem: Introduce
dev_pagemap_failure()"[1]. With the help of dax_holder and
->notify_failure() mechanism, the pmem driver is able to ask filesystem
on it to unmap all files in use, and notify processes who are using
those files.

Call trace:
trigger unbind
-> unbind_store()
-> ... (skip)
-> devres_release_all()
-> kill_dax()
-> dax_holder_notify_failure(dax_dev, 0, U64_MAX, MF_MEM_PRE_REMOVE)
-> xfs_dax_notify_failure()
`-> freeze_super() // freeze (kernel call)
`-> do xfs rmap
` -> mf_dax_kill_procs()
` -> collect_procs_fsdax() // all associated processes
` -> unmap_and_kill()
` -> invalidate_inode_pages2_range() // drop file's cache
`-> thaw_super() // thaw (both kernel & user call)

Introduce MF_MEM_PRE_REMOVE to let filesystem know this is a remove
event. Use the exclusive freeze/thaw[2] to lock the filesystem to prevent
new dax mapping from being created. Do not shutdown filesystem directly
if configuration is not supported, or if failure range includes metadata
area. Make sure all files and processes(not only the current progress)
are handled correctly. Also drop the cache of associated files before
pmem is removed.
