It's not proper to just abort IO when the map is not ready.
So revert this and requeue IO to keep consistent with the community.
And fix the deadlock introduced by the patch.

v1->v2:
  add patch 38d11da5 "dm: don't lock fs when the map is NULL in
process of resume"

Li Lingfeng (3):
  Revert "dm: make sure dm_table is binded before queue request"
  dm: don't lock fs when the map is NULL in process of resume
  dm: don't lock fs when the map is NULL during suspend or resume

Mike Snitzer (1):
  dm: requeue IO if mapping table not yet available
