      Merge tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
      
      Pull device mapper fixes from Mike Snitzer:
      
       - Fix DM integrity crash if "recalculate" used without "internal_hash"
      
       - Fix DM integrity "recalculate" support to prevent recalculating
         checksums if we use internal_hash or journal_hash with a key (e.g.
         HMAC). Use of crypto as a means to prevent malicious corruption
         requires further changes and was never a design goal for
         dm-integrity's primary usecase of detecting accidental corruption.
      
       - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix
         that was merged for 5.11-rc4.
      
       - Fix DM core's dm_get_device() to avoid filesystem lookup to get block
         device (if possible).
      
      * tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:

      After a bit of head scratching and debugging it turned out that it is
      due to kprobe handler being interrupted by a tick that causes us to go
      into (I think another) kprobe handler.
      
      The culprit was kprobe_breakpoint_ss_handler() returning DBG_HOOK_ERROR
      which leads to the Unexpected kernel BRK exception.
      
      Reverting commit ba090f9c ("arm64: kprobes: Remove redundant
      kprobe_step_ctx") seemed to fix the problem for me.
      
      Further analysis showed that kcb->kprobe_status is set to
      KPROBE_REENTER when the error occurs. By teaching
      kprobe_breakpoint_ss_handler() to handle this status I can no  longer
      reproduce the problem.
