Subject[GIT PULL] xfs: new code for 5.5
Hi Linus,

Please pull this set of new code for 5.5. 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(!)
- 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.

The branch has survived several days of xfstests runs and merges cleanly
with this morning's master. Please let me know if anything strange

FYI, Stephen Rothwell reported a merge conflict with the y2038 tree at
the end of October[1]. His resolution looked pretty straightforward,
though the current y2038 for-next branch no longer changes fs/ioctl.c
(and the changes that were in it are not in upstream master), so that
may not be necessary.



The following changes since commit c039b99792726346ad46ff17c5a5bcb77a5edac4:

iomap: use a srcmap for a read-modify-write I/O (2019-10-21 08:51:59 -0700)

xfs: allow parent directory scans to be interrupted with fatal signals (2019-11-27 08:23:14 -0800)

New code for 5.5:
- 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

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

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

- 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
