Merge tag 'xfs-5.9-merge-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"There are quite a few changes in this release, the most notable of
which is that we've made inode flushing fully asynchronous, and we no
longer block memory reclaim on this.

Furthermore, we have fixed a long-standing bug in the quota code where
soft limit warnings and inode limits were never tracked properly.

Moving further down the line, the reflink control loops have been
redesigned to behave more efficiently; and numerous small bugs have
been fixed (see below). The xattr and quota code have been extensively
refactored in preparation for more new features coming down the line.

Finally, the behavior of DAX between ext4 and xfs has been stabilized,
which gets us a step closer to removing the experimental tag from that
feature.

We have a few new contributors this time around. Welcome, all!

I anticipate a second pull request next week for a few small bugfixes
that have been trickling in, but this is it for big changes.

Summary:

- Fix some btree block pingponging problems when swapping extents

- Redesign the reflink copy loop so that we only run one remapping
operation per transaction. This helps us avoid running out of block
reservation on highly deduped filesystems.

- Take the MMAPLOCK around filemap_map_pages.

- Make inode reclaim fully async so that we avoid stalling processes
on flushing inodes to disk.

- Reduce inode cluster buffer RMW cycles by attaching the buffer to
dirty inodes so we won't let go of the cluster buffer when we know
we're going to need it soon.

- Add some more checks to the realtime bitmap file scrubber.

- Don't trip false lockdep warnings in fs freeze.

- Remove various redundant lines of code.

- Remove unnecessary calls to xfs_perag_{get,put}.

- Preserve I_VERSION state across remounts.

- Fix an unmount hang due to AIL going to sleep with a non-empty
delwri buffer list.

- Fix an error in the inode allocation space reservation macro that
caused regressions in generic/531.

- Fix a potential livelock when dquot flush fails because the dquot
buffer is locked.

- Fix a miscalculation when reserving inode quota that could cause
users to exceed a hardlimit.

- Refactor struct xfs_dquot to use native types for incore fields
instead of abusing the ondisk struct for this purpose. This will
eventually enable proper y2038+ support, but for now it merely
cleans up the quota function declarations.

- Actually increment the quota softlimit warning counter so that soft
failures turn into hard(er) failures when they exceed the softlimit
warning counter limits set by the administrator.

- Split incore dquot state flags into their own field and namespace,
to avoid mixing them with quota type flags.

- Create a new quota type flags namespace so that we can make it
obvious when a quota function takes a quota type (user, group,
project) as an argument.

- Rename the ondisk dquot flags field to type, as that more
accurately represents what we store in it.

- Drop our bespoke memory allocation flags in favor of GFP_*.

- Rearrange the xattr functions so that we no longer mix metadata
updates and transaction management (e.g. rolling complex
transactions) in the same functions. This work will prepare us for
atomic xattr operations (itself a prerequisite for directory
backrefs) in future release cycles.

- Support FS_DAX_FL (aka FS_XFLAG_DAX) via GETFLAGS/SETFLAGS"

Merge tag 'xfs-5.8-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"Most of the changes this cycle are refactoring of existing code in
preparation for things landing in the future.

We also fixed various problems and deficiencies in the quota
implementation, and (I hope) the last of the stale read vectors by
forcing write allocations to go through the unwritten state until the
write completes.

Summary:

- Various cleanups to remove dead code, unnecessary conditionals,
asserts, etc.

- Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
redundantly.

- Tighten up our dmesg logging to ensure that everything is prefixed
with 'XFS' for easier grepping.

- Kill a bunch of typedefs.

- Refactor the deferred ops code to reduce indirect function calls.

- Increase type-safety with the deferred ops code.

- Make the DAX mount options a tri-state.

- Fix some error handling problems in the inode flush code and clean
up other inode flush warts.

- Refactor log recovery so that each log item recovery functions now
live with the other log item processing code.

- Fix some SPDX forms.

- Fix quota counter corruption if the fs crashes after running
quotacheck but before any dquots get logged.

- Don't fail metadata verification on zero-entry attr leaf blocks,
since they're just part of the disk format now due to a historic
lack of log atomicity.

- Don't allow SWAPEXT between files with different [ugp]id when
quotas are enabled.

- Refactor inode fork reading and verification to run directly from
the inode-from-disk function. This means that we now actually
guarantee that _iget'ted inodes are totally verified and ready to
go.

- Move the incore inode fork format and extent counts to the ifork
structure.

- Scalability improvements by reducing cacheline pingponging in
struct xfs_mount.

- More scalability improvements by removing m_active_trans from the
hot path.

- Fix inode counter update sanity checking to run /only/ on debug
kernels.

- Fix longstanding inconsistency in what error code we return when a
program hits project quota limits (ENOSPC).

- Fix group quota returning the wrong error code when a program hits
group quota limits.

- Fix per-type quota limits and grace periods for group and project
quotas so that they actually work.

- Allow extension of individual grace periods.

- Refactor the non-reclaim inode radix tree walking code to remove a
bunch of stupid little functions and straighten out the
inconsistent naming schemes.

- Fix a bug in speculative preallocation where we measured a new
allocation based on the last extent mapping in the file instead of
looking farther for the last contiguous space allocation.

- Force delalloc writes to unwritten extents. This closes a stale
disk contents exposure vector if the system goes down before the
write completes.

- More lockdep whackamole"
