device mapper changes for 6.1

Hi Linus,

I dropped the DM ioctl changes to allow returning an error string to userspace. I rebased the unrelated earlier DM changes (from tag for-6.1/dm-changes) ontop of the 'for-6.1/dm-fix' tag... and arrived this single new tag (for-6.1/dm-changes-v2) for you to pull.

The following changes since commit bb1a1146467ad812bb65440696df0782e2bc63c8:

Merge tag 'cgroup-for-6.1-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup (2022-10-17 18:52:43 -0700)

are available in the Git repository at:
