Subject: [GIT PULL] xfs: great scads of new stuff for 4.15
Hi Linus,
This merge cycle, we're making some substantive changes to XFS. The
in-core extent mappings have been refactored to use proper iterators and
a btree to handle heavily fragmented files without needing high-order
memory allocations; some important log recovery bug fixes; and the first
part of the online fsck functionality. (The online fsck feature is
disabled by default and more pieces of it will be coming in future
release cycles.)
This giant pile of patches has been run through a full xfstests run over
the weekend and through a quick xfstests run against this morning's
master, with no major failures reported. Let me know if there's any
merge problems.

xfs: on failed mount, force-reclaim inodes after unmounting quota controls (2017-11-09 19:27:33 -0800)
----------------------------------------------------------------
New in this version:
- Refactor the incore extent map manipulations to use a cursor instead of
directly modifying extent data.
- Refactor the incore extent map cursor to use an in-memory btree instead
of a single high-order allocation. This eliminates a major source of
complaints about insufficient memory when opening a heavily fragmented
file into a system whose memory is also heavily fragmented.
- Fix a longstanding bug where deleting a file with a complex extended
attribute btree incorrectly handled memory pointers, which could lead
to memory corruption.
- Improve metadata validation to eliminate crashing problems found while
fuzzing xfs.
- Move the error injection tag definitions into libxfs to be shared with
userspace components.
- Fix some log recovery bugs where we'd underflow log block position
vector and incorrectly fail log recovery.
- Drain the buffer lru after log recovery to force recovered buffers back
through the verifiers after mount. On a v4 filesystem the log never
attaches verifiers during log replay (v5 does), so we could end up with
buffers marked verified but without having ever been verified.
- Fix various other bugs.
- Introduce the first part of a new online fsck tool. The new fsck tool
will be able to iterate every piece of metadata in the filesystem to
look for obvious errors and corruptions. In the next release cycle
the checking will be extended to cross-reference with the other fs
metadata, so this feature should only be used by the developers in the
mean time.
