Merge tag 'xfs-5.5-merge-16' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull XFS updates from Darrick Wong:
"For this release, we changed quite a few things.

Highlights:

- Fixed some long tail latency problems in the block allocator

- Removed some long deprecated (and for the past several years no-op)
mount options and ioctls

- Strengthened the extended attribute and directory verifiers

- Audited and fixed all the places where we could return EFSCORRUPTED
without logging anything

- Refactored the old SGI space allocation ioctls to make the
equivalent fallocate calls

- Fixed a race between fallocate and directio

- Fixed an integer overflow when files have more than a few
billion(!) extents

- Fixed a longstanding bug where quota accounting could be incorrect
when performing unwritten extent conversion on a freshly mounted fs

- Fixed various complaints in scrub about soft lockups and
unresponsiveness to signals

- De-vtable'd the directory handling code, which should make it
faster

- Converted to the new mount api, for better or for worse

- Cleaned up some memory leaks

and quite a lot of other smaller fixes and cleanups.

A more detailed summary:

- Fill out the build string

- Prevent inode fork extent count overflows

- Refactor the allocator to reduce long tail latency

- Rework incore log locking a little to reduce spinning

- Break up the xfs_iomap_begin functions into smaller more cohesive
parts

- Fix allocation alignment being dropped too early when the
allocation request is for more blocks than an AG is large

- Other small cleanups

- Clean up file buftarg retrieval helpers

- Hoist the resvsp and unresvsp ioctls to the vfs

- Remove the undocumented biosize mount option, since it has never
been mentioned as existing or supported on linux

- Clean up some of the mount option printing and parsing

- Enhance attr leaf verifier to check block structure

- Check dirent and attr names for invalid characters before passing
them to the vfs

- Refactor open-coded bmbt walking

- Fix a few places where we return EIO instead of EFSCORRUPTED after
failing metadata sanity checks

- Fix a synchronization problem between fallocate and aio dio
corrupting the file length

- Clean up various loose ends in the iomap and bmap code

- Convert to the new mount api

- Make sure we always log something when returning EFSCORRUPTED

- Fix some problems where long running scrub loops could trigger soft
lockup warnings and/or fail to exit due to fatal signals pending

- Fix various Coverity complaints

- Remove most of the function pointers from the directory code to
reduce indirection penalties

- Ensure that dquots are attached to the inode when performing
unwritten extent conversion after io

- Deuglify incore projid and crtime types

- Fix another AGI/AGF locking order deadlock when renaming

- Clean up some quota typedefs

- Remove the FSSETDM ioctls which haven't done anything in 20 years

- Fix some memory leaks when mounting the log fails

- Fix an underflow when updating an xattr leaf freemap

- Remove some trivial wrappers

- Report metadata corruption as an error, not a (potentially) fatal
assertion

- Clean up the dir/attr buffer mapping code

- Allow fatal signals to kill scrub during parent pointer checks"

Merge tag 'iomap-5.5-merge-11' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull iomap updates from Darrick Wong:
"In this release, we hoisted as much of XFS' writeback code into iomap
as was practicable, refactored the unshare file data function, added
the ability to perform buffered io copy on write, and tweaked various
parts of the directio implementation as needed to port ext4's directio
code (that will be a separate pull).

Summary:

- Make iomap_dio_rw callers explicitly tell us if they want us to
wait

- Port the xfs writeback code to iomap to complete the buffered io
library functions

- Refactor the unshare code to share common pieces

- Add support for performing copy on write with buffered writes

- Other minor fixes

- Fix unchecked return in iomap_bmap

- Fix a type casting bug in a ternary statement in
iomap_dio_bio_actor

- Improve tracepoints for easier diagnostic ability

- Fix pipe page leakage in directio reads"

Take the xfs writeback code and move it to fs/iomap. A new structure
with three methods is added as the abstraction from the generic writeback
code to the file system. These methods are used to map blocks, submit an
ioend, and cancel a page that encountered an error before it was added to
an ioend.
