Subject: [GIT PULL] xfs: 4.18 merge, part 1
Hi Linus,
Here's the first round of patches for XFS for 4.18. New features this
cycle include the ability to relabel mounted filesystems, support for
fallocated swapfiles, and using FUA for pure data O_DSYNC directio
writes. With this cycle we begin to integrate online filesystem repair
and refactor the growfs code in preparation for eventual subvolume
support, though the road ahead for both features is quite long.
There are also numerous refactorings of the iomap code to remove
unnecessary log overhead, to disentangle some of the quota code, and to
prepare for buffer head removal in a future upstream kernel.
Metadata validation continues to improve, both in the hot path veifiers
and the online filesystem check code. I anticipate sending a second
pull request in a few days with more metadata validation improvements.
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.
There's a merge conflict between one of the iomap refactorings and the
gfs2 changes in your master branch. The file in question is
fs/gfs2/bmap.c. I resolved the conflict and pushed the result as a
branch[1] into my git tree, and the resolved file should look like[2].
Let me know if things get hairy enough that you want me to take another
look at that.

- Reduce pointless buffer allocations during cache miss
