Merge tag 'for-4.13/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer: - a few DM integrity fixes that improve performance. One that address inefficiencies in the on-disk journal device layout. Another that makes use of the block layer's on-stack plugging when writing the journal. - a dm-bufio fix for the blk_status_t conversion that went in during the merge window. - a few DM raid fixes that address correctness when suspending the device and a validation fix for validation that occurs during device activation. - a couple DM zoned target fixes. Important one being the fix to not use GFP_KERNEL in the IO path due to concerns about deadlock in low-memory conditions (e.g. swap over a DM zoned device, etc). - a DM DAX device fix to make sure dm_dax_flush() is called if the underlying DAX device is operating as a write cache. * tag 'for-4.13/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm, dax: Make sure dm_dax_flush() is called if device supports it dm verity fec: fix GFP flags used with mempool_alloc() dm zoned: use GFP_NOIO in I/O path dm zoned: remove test for impossible REQ_OP_FLUSH conditions dm raid: bump target version dm raid: avoid mddev->suspended access dm raid: fix activation check in validate_raid_redundancy() dm raid: remove WARN_ON() in raid10_md_layout_to_format() dm bufio: fix error code in dm_bufio_write_dirty_buffers() dm integrity: test for corrupted disk format during table load dm integrity: WARN_ON if variables representing journal usage get out of sync dm integrity: use plugging when writing the journal dm integrity: fix inefficient allocation of journal space
