Merge tag 'for-4.12/dm-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- a DM verity fix for a mode when no salt is used
- a fix to DM to account for the possibility that PREFLUSH or FUA are
used without the SYNC flag if the underlying storage doesn't have a
volatile write-cache
- a DM ioctl memory allocation flag fix to use __GFP_HIGH to allow
emergency forward progress (by using memory reserves as last resort)
- a small DM integrity cleanup to use kvmalloc() instead of duplicating
the same
