# Merge: 92fff53b7191 225557446856
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'for-5.1/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper updates from Mike Snitzer:
#     
#      - Update bio-based DM core to always call blk_queue_split() and update
#        DM targets to properly advertise discard limits that
#        blk_queue_split() looks at when dtermining to split discard. Whereby
#        allowing DM core's own 'split_discard_bios' to be removed.
#     
#      - Improve DM cache target to provide support for discard passdown to
#        the origin device.
#     
#      - Introduce support to directly boot to a DM mapped device from init by
#        using dm-mod.create= module param. This eliminates the need for an
#        elaborate initramfs that is otherwise needed to create DM devices.
#     
#        This feature's implementation has been worked on for quite some time
#        (got up to v12) and is of particular interest to Android and other
#        more embedded platforms (e.g. ARM).
#     
#      - Rate limit errors from the DM integrity target that were identified
#        as the cause for recent NMI hangs due to console limitations.
#     
#      - Add sanity checks for user input to thin-pool and external snapshot
#        creation.
#     
#      - Remove some unused leftover kmem caches from when old .request_fn
#        request-based support was removed.
#     
#      - Various small cleanups and fixes to targets (e.g. typos, needless
#        unlikely() annotations, use struct_size(), remove needless
#        .direct_access method from dm-snapshot)
#     
#     * tag 'for-5.1/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
#       dm integrity: limit the rate of error messages
#       dm snapshot: don't define direct_access if we don't support it
#       dm cache: add support for discard passdown to the origin device
#       dm writecache: fix typo in name for writeback_wq
#       dm: add support to directly boot to a mapped device
#       dm thin: add sanity checks to thin-pool and external snapshot creation
#       dm block manager: remove redundant unlikely annotation
#       dm verity fec: remove redundant unlikely annotation
#       dm integrity: remove redundant unlikely annotation
#       dm: always call blk_queue_split() in dm_process_bio()
#       dm: fix to_sector() for 32bit
#       dm switch: use struct_size() in kzalloc()
#       dm: remove unused _rq_tio_cache and _rq_cache
#       dm: eliminate 'split_discard_bios' flag from DM target interface
#       dm: update dm_process_bio() to split bio if in ->make_request_fn()
