# Merge: ca7ce08d6a06 e2c789cab60a

#     Merge tag 'for-6.5/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
#     
#     Pull device mapper updates from Mike Snitzer:
#     
#      - Update DM crypt to allocate compound pages if possible
#     
#      - Fix DM crypt target's crypt_ctr_cipher_new return value on invalid
#        AEAD cipher
#     
#      - Fix DM flakey testing target's write bio corruption feature to
#        corrupt the data of a cloned bio instead of the original
#     
#      - Add random_read_corrupt and random_write_corrupt features to DM
#        flakey target
#     
#      - Fix ABBA deadlock in DM thin metadata by resetting associated bufio
#        client rather than destroying and recreating it
#     
#      - A couple other small DM thinp cleanups
#     
#      - Update DM core to support disabling block core IO stats accounting
#        and optimize away code that isn't needed if stats are disabled
#     
#      - Other small DM core cleanups
#     
#      - Improve DM integrity target to not require so much memory on 32 bit
#        systems. Also only allocate the recalculate buffer as needed (and
#        increasingly reduce its size on allocation failure)
#     
#      - Update DM integrity to use %*ph for printing hexdump of a small
#        buffer. Also update DM integrity documentation
#     
#      - Various DM core ioctl interface hardening. Now more careful about
#        alignment of structures and processing of input passed to the kernel
#        from userspace.
#     
#        Also disallow the creation of DM devices named "control", "." or ".."
#     
#      - Eliminate GFP_NOIO workarounds for __vmalloc and kvmalloc in DM
#        core's ioctl and bufio code
#     
#     * tag 'for-6.5/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (28 commits)
#       dm: get rid of GFP_NOIO workarounds for __vmalloc and kvmalloc
#       dm integrity: scale down the recalculate buffer if memory allocation fails
#       dm integrity: only allocate recalculate buffer when needed
#       dm integrity: reduce vmalloc space footprint on 32-bit architectures
#       dm ioctl: Refuse to create device named "." or ".."
#       dm ioctl: Refuse to create device named "control"
#       dm ioctl: Avoid double-fetch of version
#       dm ioctl: structs and parameter strings must not overlap
#       dm ioctl: Avoid pointer arithmetic overflow
#       dm ioctl: Check dm_target_spec is sufficiently aligned
#       Documentation: dm-integrity: Document an example of how the tunables relate.
#       Documentation: dm-integrity: Document default values.
#       Documentation: dm-integrity: Document the meaning of "buffer".
#       Documentation: dm-integrity: Fix minor grammatical error.
#       dm integrity: Use %*ph for printing hexdump of a small buffer
#       dm thin: disable discards for thin-pool if no_discard_passdown
#       dm: remove stale/redundant dm_internal_{suspend,resume} prototypes in dm.h
#       dm: skip dm-stats work in alloc_io() unless needed
#       dm: avoid needless dm_io access if all IO accounting is disabled
#       dm: support turning off block-core's io stats accounting
