Hi Linus,
Please pull this branch containing new XFS code for 6.0. 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.
As usual, I did a test-merge with upstream master as of a few minutes
ago, and it completed flawlessly. Please let me know if you encounter
any problems. Hopefully I got the merge commits from Dave's pull
requests landed correctly, since I'm a bit rusty on that.

xfs: delete extra space and tab in blank line (2022-07-31 09:21:27 -0700)
----------------------------------------------------------------
New code for 5.20:
- 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.
