Merge tag 'xfs-4.14-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs fixes from Darrick Wong: - fix various problems with the copy-on-write extent maps getting freed at the wrong time - fix printk format specifier problems - report zeroing operation outcomes instead of dropping them on the floor - fix some crashes when dio operations partially fail - fix a race condition between unwritten extent conversion & dio read - fix some incorrect tests in the inode log item processing - correct the delayed allocation space reservations on rmap filesystems - fix some problems checking for dax support * tag 'xfs-4.14-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: revert "xfs: factor rmap btree size into the indlen calculations" xfs: Capture state of the right inode in xfs_iflush_done xfs: perag initialization should only touch m_ag_max_usable for AG 0 xfs: update i_size after unwritten conversion in dio completion iomap_dio_rw: Allocate AIO completion queue before submitting dio xfs: validate bdev support for DAX inode flag xfs: remove redundant re-initialization of total_nr_pages xfs: Output warning message when discard option was enabled even though the device does not support discard xfs: report zeroed or not correctly in xfs_zero_range() xfs: kill meaningless variable 'zero' fs/xfs: Use %pS printk format for direct addresses xfs: evict CoW fork extents when performing finsert/fcollapse xfs: don't unconditionally clear the reflink flag on zero-block files
