[v2,0/2] dm cache: support shrinking the origin device

Message

This patch series introduces formal support for shrinking the cache
origin and ensures that failed resume attempts, such as those caused
by shrinking failures, do not trigger BUG_ON.

The only change in v2 patchset is the updated dm-cache's version number.

  dm cache: prevent BUG_ON by blocking retries on failed device resumes
  dm cache: support shrinking the origin device
