Merge tag 'for-4.20/dm-fixes' of git://git./linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- Fix DM cache metadata to verify that a cache has block before trying
to continue with operation that requires them.
- Fix bio-based DM core's dm_make_request() to properly impose device
limits on individual bios by making use of blk_queue_split().
- Fix long-standing race with how DM thinp notified userspace of
thin-pool mode state changes before they were actually made.
- Fix the zoned target's bio completion handling; this is a fairly
invassive fix at this stage but it is localized to the zoned target.
Any zoned target users will benefit from this fix.
