Hi Linus,

Please pull this first batch of new changes for 5.7.  There's a lot
going on this cycle with cleanups in the log code, the btree code, and
the xattr code.  We're tightening of metadata validation and online fsck
checking, and introducing a common btree rebuilding library so that we
can refactor xfs_repair and introduce online repair in a future cycle.
We also fixed a few visible bugs -- most notably there's one in getdents
that we introduced in 5.6; and a fix for hangs when disabling quotas.

This series has been running fstests & other QA in the background for
over a week and looks good so far.  I just did a test merge and it seems
to go in cleanly, so please let me know if you encounter any surprises.

I anticipate sending you a second pull request next week.  That batch
will change how xfs interacts with memory reclaim; how the log batches
and throttles log items; how hard writes near ENOSPC will try to squeeze
more space out of the filesystem; and hopefully fix the last of the
umount hangs after a catastrophic failure.  That should ease a lot of
problems when running at the limits, but for now I'm leaving that in
for-next for another week to make sure we got all the subtleties right.

  xfs: prohibit fs freezing when using empty transactions (2020-03-26 08:19:24 -0700)

----------------------------------------------------------------
New code for 5.7:
 - Fix a hard to trigger race between iclog error checking and log shutdown.
 - Strengthen the AGF verifier.
 - Ratelimit some of the more spammy error messages.
 - Remove the icdinode uid/gid members and just use the ones in the vfs inode.
 - Hold ILOCK across insert/collapse range.
 - Clean up the extended attribute interfaces.
 - Clean up the attr flags mess.
 - Restore PF_MEMALLOC after exiting xfsaild thread to avoid triggering
   warnings in the process accounting code.
 - Remove the flexibly-sized array from struct xfs_agfl to eliminate
   compiler warnings about unaligned pointers and packed structures.
 - Various macro and typedef removals.
 - Stale metadata buffers if we decide they're corrupt outside of a
   verifier.
 - Check directory data/block/free block owners.
 - Fix a UAF when aborting inactivation of a corrupt xattr fork.
 - Teach online scrub to report failed directory and attr name lookups
   as a metadata corruption instead of a runtime error.
 - Avoid potential buffer overflows in sysfs files by using scnprintf.
 - Fix a regression in getdents lookups due to a mistake in pointer
   arithmetic.
 - Refactor btree cursor private data structures to use anonymous
   unions.
 - Cleanups in the log unmounting code.
 - Fix a potential mishandling of ENOMEM errors on multi-block directory
   buffer lookups.
 - Fix an incorrect test in the block allocation code.
 - Cleanups and name prefix shortening in the scrub code.
 - Introduce btree bulk loading code for online repair and scrub.
 - Fix a quotaoff log item leak (and hang) when the fs goes down midway
   through a quotaoff operation.
 - Remove di_version from the incore inode.
 - Refactor some of the log shutdown checking code.
 - Record the forcing of the log unmount records in the log force
   counters.
 - Fix a longstanding bug where quotacheck would purge the
   administrator's default quota grace interval and warning limits.
 - Reduce memory usage when scrubbing directory and xattr trees.
 - Don't let fsfreeze race with GETFSMAP or online scrub.
 - Handle bio_add_page failures more gracefully in xlog_write_iclog.
