Subject[GIT PULL] xfs: new code for 5.14
Hi Linus,

Please pull this branch containing new code for 5.14. Most of the work
this cycle has been on refactoring various parts of the codebase. The
biggest non-cleanup changes are (1) reducing the number of cache flushes
sent when writing the log; (2) a substantial number of log recovery
fixes; and (3) I started accepting pull requests from contributors if
the commits in their branches match what's been sent to the list.

For a week or so I /had/ staged a major cleanup of the logging code from
Dave Chinner, but it exposed so many lurking bugs in other parts of the
logging and log recovery code that I decided to defer that patchset
until we can address those latent bugs.

Larger cleanups this time include walking the incore inode cache (me)
and rework of the extended attribute code (Allison) to prepare it for
adding logged xattr updates (and directory tree parent pointers) in
future releases.

The branch merges cleanly against upstream as of a few minutes ago.
Please let me know if anything else strange happens during the merge
process. The merge commits I made seem stable enough, but as it's the
first time I've ever accepted a pull request, we'd all be open to
feedback for improvements for next time.

xfs: don't wait on future iclogs when pushing the CIL (2021-06-25 14:02:02 -0700)

----------------------------------------------------------------
New code for 5.14:
- Refactor the buffer cache to use bulk page allocation
- Convert agnumber-based AG iteration to walk per-AG structures
- Clean up some unit conversions and other code warts
- Reduce spinlock contention in the directio fastpath
- Collapse all the inode cache walks into a single function
- Remove indirect function calls from the inode cache walk code
- Dramatically reduce the number of cache flushes sent when writing log
buffers
- Preserve inode sickness reports for longer
- Rename xfs_eofblocks since it controls inode cache walks
- Refactor the extended attribute code to prepare it for the addition
of log intent items to make xattrs fully transactional
- A few fixes to earlier large patchsets
- Log recovery fixes so that we don't accidentally mark the log clean
when log intent recovery fails
- Fix some latent SOB errors
- Clean up shutdown messages that get logged to dmesg
- Fix a regression in the online shrink code
- Fix a UAF in the buffer logging code if the fs goes offline
- Fix uninitialized error variables
- Fix a UAF in the CIL when commited log item callbacks race with a
shutdown
- Fix a bug where the CIL could hang trying to push part of the log ring
buffer that hasn't been filled yet
