[v3,0/2] 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 v3 patchset fixes the bitwise casting warning reported by sparse.

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