Merge tag 'xfs-5.2-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
ability to report metadata health status to userspace after online
fsck checks the filesystem. The online metadata checking code is (I
really hope) feature complete with the addition of checks for the
global fs counters, though it'll remain EXPERIMENTAL for now.
There are also fixes for thundering herds of writeback completions and
some other deadlocks, fixes for theoretical integer overflow attacks
on space accounting, and removal of the long-defunct 'mntpt' option
which was deprecated in the mid-2000s and (it turns out) totally
broken since 2011 (and nobody complained...).
Summary:
- Fix some more buffer deadlocks when performing an unmount after a
hard shutdown.
- Fix some minor space accounting issues.
- Fix some use after free problems.
- Make the (undocumented) FITRIM behavior consistent with other
filesystems.
- Embiggen the xfs geometry ioctl's data structure.
- Introduce a new AG geometry ioctl.
- Introduce a new online health reporting infrastructure and ioctl
for userspace to query a filesystem's health status.
- Enhance online scrub and repair to update the health reports.
- Reduce thundering herd problems when writeback io completes.
- Fix some transaction reservation type errors.
- Fix integer overflow problems with delayed alloc reservation
counters.
- Fix some problems where we would exit to userspace without
unlocking.
- Fix inconsistent behavior when finishing deferred ops fails.
- Strengthen scrub to check incore data against ondisk metadata.
- Remove long-broken mntpt mount option.
- Add an online scrub function for the filesystem summary counters,
which should make online metadata scrub more or less feature
complete for now.
- Various cleanups"
