- 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.

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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
