Hi Linus,

Please pull this second batch of new changes for 5.7.  As promised last
week, this batch changes 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.

This branch merges cleanly with master as of a few minutes ago, so
please let me know if anything strange happens.

The following changes since commit 27fb5a72f50aa770dd38b0478c07acacef97e3e7:

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

  xfs: reflink should force the log out if mounted with wsync (2020-04-06 08:44:39 -0700)

----------------------------------------------------------------
(More) new code for 5.7:
- Validate the realtime geometry in the superblock when mounting
- Refactor a bunch of tricky flag handling in the log code
- Flush the CIL more judiciously so that we don't wait until there are
  millions of log items consuming a lot of memory.
- Throttle transaction commits to prevent the xfs frontend from flooding
  the CIL with too many log items.
- Account metadata buffers correctly for memory reclaim.
- Mark slabs properly for memory reclaim.  These should help reclaim run
  more effectively when XFS is using a lot of memory.
- Don't write a garbage log record at unmount time if we're trying to
  trigger summary counter recalculation at next mount.
- Don't block the AIL on locked dquot/inode buffers; instead trigger its
  backoff mechanism to give the lock holder a chance to finish up.
- Ratelimit writeback flushing when buffered writes encounter ENOSPC.
- Other minor cleanups.
- Make reflink a synchronous operation when the fs is mounted with wsync
  or sync, which means that now we force the log to disk to record the
  changes.
