Subject: [GIT PULL] xfs: 4.19 merge, part 2
Hi Linus,
This is the second part of the XFS changes for 4.19. The biggest
changes are the removal of buffer heads frm XFS, a massive reworking of
the deferred transaction operations handling code, the removal of the
long defunct barrier/nobarrier mount options, and the addition of a
few more online repair functions.
I started by merging the iomap-4.19-merge branch atop v4.18-rc4 and then
merging in all the development branches as they came ready. I hope that
won't mess up the pull process (it seemed to work fine with the current
master) but please let us know if there are any problems.
(FWIW I also sustained an eye injury last week so it may take a day to
respond.)

xfs: fix a null pointer dereference in xfs_bmap_extents_to_btree (2018-08-12 08:37:31 -0700)
----------------------------------------------------------------
Changes for 4.19:
- Use extent maps to track pagecache page status instead of bufferhead
state.
- Refactor pagecache read and write paths to use the new iomap library
functions, which enable us to drop the old bufferhead code for
pagesize == blocksize filesystems.
- Set up parallel per-block-per-page metadata to track subpage
information that was tracked by buffer heads, which enables us to drop
the old bufferhead code for pagesize > blocksize filesystems.
- Tie a deferred ops control structure to a transaction so that we can
take advantage of an upper-level dfops without having to plumb pointer
passing through the code.
- Refactor the deferred ops code to track deferred ops as part of the
transaction structure (instead of as a separate data structure) so
that we can simplify the scoping rules around defer_ops.
- Refactor twisty delwri buffer submission code to avoid deadlocks.
- Shorten and fix indenting problems in the scrub code.
- Detect obviously bad summary counts at mount and fix them.
- Directly associate deferred ops control structure with a transaction
so that callers no longer have to manage it themselves.
- Remove a couple of IRIX-era inode macros.
- Remove the long-deprecated 'barrier' and 'nobarrier' mount options.
- Clean up the inode fork structure a bit.
- Check for bad fs summary counter values in the superblock.
- Reduce COW fork lookups during writeback.
- Refactor the deferred ops control structures into the transaction
structure, thereby eliminating the need for transaction users to
handle the deferred ops as a separate data structure.
- Add the ability to repair AG headers online.
- Fix a crash due to insufficient return value checking.
- Various fixes and cleanups.
