Merge tag 'for-6.0/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull more device mapper updates from Mike Snitzer:

 - Add flags argument to dm_bufio_client_create and introduce
   DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather
   than mutex for its locking.

 - Add optional "try_verify_in_tasklet" feature to DM verity target.
   This feature gives users the option to improve IO latency by using a
   tasklet to verify, using hashes in bufio's cache, rather than wait to
   schedule a work item via workqueue. But if there is a bufio cache
   miss, or an error, then the tasklet will fallback to using workqueue.

 - Incremental changes to both dm-bufio and the DM verity target to use
   jump_label to minimize cost of branching associated with the niche
   "try_verify_in_tasklet" feature. DM-bufio in particular is used by
   quite a few other DM targets so it doesn't make sense to incur
   additional bufio cost in those targets purely for the benefit of this
   niche verity feature if the feature isn't ever used.

 - Optimize verity_verify_io, which is used by both workqueue and
   tasklet based verification, if FEC is not configured or tasklet based
   verification isn't used.

 - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE
   flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if
   "try_verify_in_tasklet" is specified.
