# Merge: c993e07be023 12907efde6ad
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     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.
#
