Merge tag 'xfs-4.19-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"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.
Summary:
- 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"
