Merge tag 'for-6.10/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper fixes from Mike Snitzer:

 - Fix DM discard regressions due to DM core switching over to using
   queue_limits_set() without DM core and targets first being updated to
   set (and stack) discard limits in terms of max_hw_discard_sectors and
   not max_discard_sectors

 - Fix stable@ DM integrity discard support to set device's
   discard_granularity limit to the device's logical block size

* tag 'for-6.10/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
  dm: always manage discard support in terms of max_hw_discard_sectors
  dm-integrity: set discard_granularity to logical block size
