Hi Linus,
Here are some patches for 4.18 to fix regressions, accounting problems,
overflow problems, and to strengthen metadata validation to prevent
corruption.
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.

xfs: fix fdblocks accounting w/ RMAPBT per-AG reservation (2018-06-24 12:00:12 -0700)
----------------------------------------------------------------
Changes since last update:
- More metadata validation strengthening to prevent crashes.
- Fix extent offset overflow problem when insert_range on a 512b block fs
- Fix some off-by-one errors in the realtime fsmap code
- Fix some math errors in the default resblks calculation when free space
is low
- Fix a problem where stale page contents are exposed via mmap read
after a zero_range at eof
- Fix accounting problems with per-ag reservations causing statfs
reports to vary incorrectly
----------------------------------------------------------------
Christoph Hellwig (1):
xfs: simplify xfs_bmap_punch_delalloc_range
Darrick J. Wong (8):
xfs: allow empty transactions while frozen
xfs: don't trip over negative free space in xfs_reserve_blocks
xfs: don't allow insert-range to shift extents past the maximum offset
xfs: recheck reflink state after grabbing ILOCK_SHARED for a write
xfs: fix uninitialized field in rtbitmap fsmap backend
xfs: fix off-by-one error in xfs_rtalloc_query_range
xfs: ensure post-EOF zeroing happens after zeroing part of a file
xfs: fix fdblocks accounting w/ RMAPBT per-AG reservation
Dave Chinner (2):
xfs: More robust inode extent count validation
xfs: xfs_iflush_abort() can be called twice on cluster writeback failure

Hi Linus,
Here are a couple of late patches for 4.18 to fix a coding bug
introduced in -rc1 and a fix for incorrect metadata verification of
on-disk data.
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.
