Pull xfs updates from Darrick Wong:
"There's a lot going on this time, which seems about right for this
drama-filled year.

Community developers added some code to speed up freezing when
read-only workloads are still running, refactored the logging code,
added checks to prevent file extent counter overflow, reduced iolock
cycling to speed up fsync and gc scans, and started the slow march
towards supporting filesystem shrinking.

There's a huge refactoring of the internal speculative preallocation
garbage collection code which fixes a bunch of bugs, makes the gc
scheduling per-AG and hence multithreaded, and standardizes the retry
logic when we try to reserve space or quota, can't, and want to
trigger a gc scan. We also enable multithreaded quotacheck to reduce
mount times further. This is also preparation for background file gc,
which may or may not land for 5.13.

We also fixed some deadlocks in the rename code, fixed a quota
accounting leak when FSSETXATTR fails, restored the behavior that
write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
where sgid directory inheritance wasn't quite working properly, and
fixed a bug where symlinks weren't working properly in ecryptfs. We
also now advertise the inode btree counters feature that was
introduced two cycles ago.

Summary:

- Fix an ABBA deadlock when renaming files on overlayfs.

- Make sure that we can't overflow the inode extent counters when
adding to or removing extents from a file.

- Make directory sgid inheritance work the same way as all the other
filesystems.

- Don't drain the buffer cache on freeze and ro remount, which should
reduce the amount of time if read-only workloads are continuing
during the freeze.

- Fix a bug where symlink size isn't reported to the vfs in ecryptfs.

- Disentangle log cleaning from log covering. This refactoring sets
us up for future changes to the log, though for now it simply means
that we can use covering for freezes, and cleaning becomes
something we only do at unmount.

- Speed up file fsyncs by reducing iolock cycling.

- Fix delalloc blocks leaking when changing the project id fails
because of input validation errors in FSSETXATTR.

- Fix oversized quota reservation when converting unwritten extents
during a DAX write.

- Create a transaction allocation helper function to standardize the
idiom of allocating a transaction, reserving blocks, locking
inodes, and reserving quota. Replace all the open-coded logic for
file creation, file ownership changes, and file modifications to
use them.

- Actually shut down the fs if the incore quota reservations get
corrupted.

- Fix background block garbage collection scans to not block and to
actually clean out CoW staging extents properly.

- Run block gc scans when we run low on project quota.

- Use the standardized transaction allocation helpers to make it so
that ENOSPC and EDQUOT errors during reservation will back out,
invoke the block gc scanner, and try again. This is preparation for
introducing background inode garbage collection in the next cycle.

- Combine speculative post-EOF block garbage collection with
speculative copy on write block garbage collection.

- Enable multithreaded quotacheck.

- Allow sysadmins to tweak the CPU affinities and maximum concurrency
levels of quotacheck and background blockgc worker pools.

- Expose the inode btree counter feature in the fs geometry ioctl.

- Cleanups of the growfs code in preparation for starting work on
filesystem shrinking.

- Fix all the bloody gcc warnings that the maintainer knows about. :P

- Fix a RST syntax error.

- Don't trigger bmbt corruption assertions after the fs shuts down.

- Restore behavior of forcing SIGBUS on a shut down filesystem when
someone triggers a mmap write fault (or really, any buffered
write)"

xfs: refactor inode ownership change transaction/inode/quota allocation idiom

For file ownership (uid, gid, prid) changes, create a new helper
xfs_trans_alloc_ichange that allocates a transaction and reserves the
appropriate amount of quota against that transction in preparation for a
change of user, group, or project id. Replace all the open-coded idioms
with a single call to this helper so that we can contain the retry loops
in the next patchset.

This changes the locking behavior for ichange transactions slightly.
Since tr_ichange does not have a permanent reservation and cannot roll,
we pass XFS_ILOCK_EXCL to ijoin so that the inode will be unlocked
automatically at commit time.

Note that full-filesystem bulkstat is not supported from inside idmapped
mounts as it is an administrative operation that acts on the whole file
system. The limitation is not applied to the bulkstat single operation
that just operates on a single inode.

fs: make helpers idmap mount aware

Extend some inode methods with an additional user namespace argument. A
filesystem that is aware of idmapped mounts will receive the user
namespace the mount has been marked with. This can be used for
additional permission checking and also to enable filesystems to
translate between uids and gids if they need to. We have implemented all
relevant helpers in earlier patches.

As requested we simply extend the exisiting inode method instead of
introducing new ones. This is a little more code churn but it's mostly
mechanical and doesnt't leave us with additional inode methods.

acl: handle idmapped mounts

The posix acl permission checking helpers determine whether a caller is
privileged over an inode according to the acls associated with the
inode. Add helpers that make it possible to handle acls on idmapped
mounts.

The vfs and the filesystems targeted by this first iteration make use of
posix_acl_fix_xattr_from_user() and posix_acl_fix_xattr_to_user() to
translate basic posix access and default permissions such as the
ACL_USER and ACL_GROUP type according to the initial user namespace (or
the superblock's user namespace) to and from the caller's current user
namespace. Adapt these two helpers to handle idmapped mounts whereby we
either map from or into the mount's user namespace depending on in which
direction we're translating.
Similarly, cap_convert_nscap() is used by the vfs to translate user
namespace and non-user namespace aware filesystem capabilities from the
superblock's user namespace to the caller's user namespace. Enable it to
handle idmapped mounts by accounting for the mount's user namespace.

In addition the fileystems targeted in the first iteration of this patch
series make use of the posix_acl_chmod() and, posix_acl_update_mode()
helpers. Both helpers perform permission checks on the target inode. Let
them handle idmapped mounts. These two helpers are called when posix
acls are set by the respective filesystems to handle this case we extend
the ->set() method to take an additional user namespace argument to pass
the mount's user namespace down.

attr: handle idmapped mounts

When file attributes are changed most filesystems rely on the
setattr_prepare(), setattr_copy(), and notify_change() helpers for
initialization and permission checking. Let them handle idmapped mounts.
If the inode is accessed through an idmapped mount map it into the
mount's user namespace. Afterwards the checks are identical to
non-idmapped mounts. If the initial user namespace is passed nothing
changes so non-idmapped mounts will see identical behavior as before.

Helpers that perform checks on the ia_uid and ia_gid fields in struct
iattr assume that ia_uid and ia_gid are intended values and have already
been mapped correctly at the userspace-kernelspace boundary as we
already do today. If the initial user namespace is passed nothing
changes so non-idmapped mounts will see identical behavior as before.

Pull xfs updates from Darrick Wong:
"In this release we add the ability to set a 'needsrepair' flag
indicating that we /know/ the filesystem requires xfs_repair, but
other than that, it's the usual strengthening of metadata validation
and miscellaneous cleanups.

Summary:

- Introduce a "needsrepair" "feature" to flag a filesystem as needing
a pass through xfs_repair. This is key to enabling filesystem
upgrades (in xfs_db) that require xfs_repair to make minor
adjustments to metadata.

- Refactor parameter checking of recovered log intent items so that
we actually use the same validation code as them that generate the
intent items.

- Various fixes to online scrub not reacting correctly to directory
entries pointing to inodes that cannot be igetted.

- Refactor validation helpers for data and rt volume extents.

- Refactor XFS_TRANS_DQ_DIRTY out of existence.

- Fix a longstanding bug where mounting with "uqnoenforce" would
start user quotas in non-enforcing mode but /proc/mounts would
display "usrquota", implying that they are being enforced.

- Don't flag dax+reflink inodes as corruption since that is a valid
(but not fully functional) combination right now.

- Clean up raid stripe validation functions.

- Refactor the inode allocation code to be more straightforward.

- Small prep cleanup for idmapping support.

- Get rid of the xfs_buf_t typedef"
