Pull device mapper updates from Mikulas Patocka:

 - better error handling when reloading a table

 - use use generic disable_* functions instead of open coding them

 - lock queue limits when reading them

 - remove unneeded kvfree from alloc_targets

 - fix BLK_FEAT_ATOMIC_WRITES

 - pass through operations on wrapped inline crypto keys

 - dm-verity:
     - use softirq context only when !need_resched()
     - fix a memory leak if some arguments are specified multiple times

 - dm-mpath:
    - interface for explicit probing of active paths
    - replace spin_lock_irqsave with spin_lock_irq

 - dm-delay: don't busy-wait in kthread

 - dm-bufio: remove maximum age based eviction

 - dm-flakey: various fixes

 - vdo indexer: don't read request structure after enqueuing

 - dm-zone: Use bdev_*() helper functions where applicable

 - dm-mirror: fix a tiny race condition

 - dm-stripe: small code cleanup
