Merge tag 'xfs-5.20-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"The biggest changes for this release are the log scalability
improvements, lockless lookups for the buffer cache, and making the
attr fork a permanent part of the incore inode in preparation for
directory parent pointers.

There's also a bunch of bug fixes that have accumulated since -rc5. I
might send you a second pull request with some more bug fixes that I'm
still working on.

Once the merge window ends, I will hand maintainership back to Dave
Chinner until the 6.1-rc1 release so that I can conduct the design
review for the online fsck feature, and try to get it merged.

Summary:

- Improve scalability of the XFS log by removing spinlocks and global
synchronization points.

- Add security labels to whiteout inodes to match the other
filesystems.

- Clean up per-ag pointer passing to simplify call sites.

- Reduce verifier overhead by precalculating more AG geometry.

- Implement fast-path lockless lookups in the buffer cache to reduce
spinlock hammering.

- Make attr forks a permanent part of the inode structure to fix a
UAF bug and because most files these days tend to have security
labels and soon will have parent pointers too.

- Clean up XFS_IFORK_Q usage and give it a better name.

- Fix more UAF bugs in the xattr code.

- SOB my tags.

- Fix some typos in the timestamp range documentation.

- Fix a few more memory leaks.

- Code cleanups and typo fixes.

- Fix an unlocked inode fork pointer access in getbmap"

xfs: make attr forks permanent

This series fixes a use-after-free bug that syzbot uncovered. The UAF
itself is a result of a race condition between getxattr and removexattr
because callers to getxattr do not necessarily take any sort of locks
before calling into the filesystem.

Although the race condition itself can be fixed through clever use of a
memory barrier, further consideration of the use cases of extended
attributes shows that most files always have at least one attribute, so
we might as well make them permanent.

v2: Minor tweaks suggested by Dave, and convert some more macros to
helper functions.
