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"

struct xfs_defer_ops has now been reduced to a single list_head. The

Merge branch 'iomap-write' into linux-gfs2/for-next

Pull in the gfs2 iomap-write changes: Tweak the existing code to
properly support iomap write and eliminate an unnecessary special case
in gfs2_block_map. Implement iomap write support for buffered and
direct I/O. Simplify some of the existing code and eliminate code that
is no longer used:

gfs2: Remove gfs2_write_{begin,end}
gfs2: iomap direct I/O support
gfs2: gfs2_extent_length cleanup
gfs2: iomap buffered write support
gfs2: Further iomap cleanups

This is based on the following changes on the xfs 'iomap-4.19-merge'
branch:

iomap: add private pointer to struct iomap
iomap: add a page_done callback
iomap: generic inline data handling
iomap: complete partial direct I/O writes synchronously
iomap: mark newly allocated buffer heads as new
fs: factor out a __generic_write_end helper

xfs: use ->t_firstblock in xattr ops

Similar to the dirops code, the xattr code uses an on-stack
firstblock variable for the various operations. This code rolls the
underlying transaction in various places, however, which means we
cannot simply replace the local firstblock vars with ->t_firstblock.
Doing so (without further changes) would invalidate the memory
pointed to by xfs_da_args.firstblock as soon as the first
transaction rolls.

To avoid this problem, remove xfs_da_args.firstblock and replace all
such accesses with ->t_firstblock at the same time. This ensures
that accesses to the current firstblock always occur through the
current transaction rather than a potentially invalid xfs_da_args
pointer.

"Here's the second round of patches for XFS for 4.18. Most of the
commits are small cleanups, bug fixes, and continued strengthening of
metadata verifiers; the bulk of the diff is the conversion of the
fs/xfs/ tree to use SPDX tags.

This series 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.

Summary:

- Strengthen metadata checking to avoid ASSERTing on bad disk
contents

- Validate btree records that are being retrieved for clients

- Strengthen root inode verification

- Convert license blurbs to SPDX tags

- Enable changing DAX flag on directories

- Fix some writeback deadlocks in reflink

- Refactor out some old xfs helpers

- Move type verifiers to a separate file

- Fix some fuzzer crashes

xfs: convert to SPDX license tags

Remove the verbose license text from XFS files and replace them
with SPDX tags. This does not change the license of any of the code,
merely refers to the common, up-to-date license files in LICENSES/

This change was mostly scripted. fs/xfs/Makefile and
fs/xfs/libxfs/xfs_fs.h were modified by hand, the rest were detected
and modified by the following command:

for f in `git grep -l "GNU General" fs/xfs/` ; do
echo $f
cat $f | awk -f hdr.awk > $f.new
mv -f $f.new $f
done

And the hdr.awk script that did the modification (including
detecting the difference between GPL-2.0 and GPL-2.0+ licenses)
is as follows:

$ cat hdr.awk
BEGIN {
hdr = 1.0
tag = "GPL-2.0"
str = ""
}

/^ \* This program is free software/ {
hdr = 2.0;
