Pull btrfs updates from David Sterba:
"This time the majority of changes are cleanups, though there's still a
number of changes of user interest.

User visible changes:

- better read time and write checks to catch errors early and before
writing data to disk (to catch potential memory corruption on data
that get checksummed)

- qgroups + metadata relocation: last speed up patch int the series
to address the slowness, there should be no overhead comparing
balance with and without qgroups

- FIEMAP ioctl does not start a transaction unnecessarily, this can
result in a speed up and less blocking due to IO

- LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this
can speed up the mentioned ioctl and scrub as well

- fsync on files with many (but not too many) hardlinks is faster,
finer decision if the links should be fsynced individually or
completely

- send tries harder to find ranges to clone

- trim/discard will skip unallocated chunks that haven't been touched
since the last mount

Fixes:

- send flushes delayed allocation before start, otherwise it could
miss some changes in case of a very recent rw->ro switch of a
subvolume

- fix fallocate with qgroups that could lead to space accounting
underflow, reported as a warning

- trim/discard ioctl honours the requested range

- starting send and dedupe on a subvolume at the same time will let
only one of them succeed, this is to prevent changes that send
could miss due to dedupe; both operations are restartable

Core changes:

- more tree-checker validations, errors reported by fuzzing tools:
- device item
- inode item
- block group profiles

- tracepoints for extent buffer locking

- async cow preallocates memory to avoid errors happening too deep in
the call chain

- metadata reservations for delalloc reworked to better adapt in
many-writers/low-space scenarios

- improved space flushing logic for intense DIO vs buffered workloads

- lots of cleanups
- removed unused struct members
- redundant argument removal
- properties and xattrs
- extent buffer locking
- selftests
- use common file type conversions
- many-argument functions reduction"

Merge tag 'for-4.21-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
"New features:

- swapfile support - after a long time it's here, with some
limitations where COW design does not work well with the swap
implementation (nodatacow file, no compression, cannot be
snapshotted, not possible on multiple devices, ...), as this is the
most restricted but working setup, we'll try to improve that in the
future

- metadata uuid - an optional incompat feature to assign a new
filesystem UUID without overwriting all metadata blocks, stored
only in superblock

- more balance messages are printed to system log, initial is in the
format of the command line that would be used to start it

Fixes:

- tag pages of a snapshot to better separate pages that are involved
in the snapshot (and need to get synced) from newly dirtied pages
that could slow down or even livelock the snapshot operation

- improved check of filesystem id associated with a device during
scan to detect duplicate devices that could be mixed up during
mount

- fix device replace state transitions, eg. when it ends up
interrupted and reboot tries to restart balance too, or when
start/cancel ioctls race

- fix a crash due to a race when quotas are enabled during snapshot
creation

- GFP_NOFS/memalloc_nofs_* fixes due to GFP_KERNEL allocations in
transaction context

- fix fsync of files with multiple hard links in new directories

- fix race of send with transaction commits that create snapshots

Core changes:

- cleanups:
* further removals of now-dead fsync code
* core function for finding free extent has been split and
provides a base for further cleanups to make the logic more
understandable
* removed lot of indirect callbacks for data and metadata inodes
* simplified refcounting and locking for cloned extent buffers
* removed redundant function arguments
* defines converted to enums where appropriate

- separate reserve for delayed refs from global reserve, update logic
to do less trickery and ad-hoc heuristics, move out some related
expensive operations from transaction commit or file truncate

- dev-replace switched from custom locking scheme to semaphore

- remove first phase of balance that tried to make some space for the
relocation by calling shrink and grow, this did not work as
expected and only introduced more error states due to potential
resize failures, slightly improves the runtime as the chunks on all
devices are not needlessly enumerated

- clone and deduplication now use generic helper that adds a few more
checks that were missing from the original btrfs implementation of
the ioctls"

Btrfs: remove no longer used io_err from btrfs_log_ctx

The io_err field of struct btrfs_log_ctx is no longer used after the
recent simplification of the fast fsync path, where we now wait for
ordered extents to complete before logging the inode. We did this in
commit b5e6c3e170b7 ("btrfs: always wait on ordered extents at fsync
time") and commit a2120a473a80 ("btrfs: clean up the left over
logged_list usage") removed its last use.
