  dm cache metadata: fail operations if fail_io mode has been established (2017-05-05 14:40:13 -0400)

Please pull, thanks.
Mike

----------------------------------------------------------------
- DM cache metadata fixes to short-circuit operations that require the
  metadata not be in 'fail_io' mode.  Otherwise crashes are possible.

- a DM cache fix to address the inability to adapt to continuous IO that
  happened to also reflect a changing working set (which required old
  blocks be demoted before the new working set could be promoted)

- a DM cache smq policy cleanup that fell out from reviewing the above

- fix the Kconfig help text for CONFIG_DM_INTEGRITY

----------------------------------------------------------------
Joe Thornber (1):
      dm cache policy smq: allow demotions to happen even during continuous IO

Mike Snitzer (3):
      dm cache policy smq: cleanup free_target_met() and clean_target_met()
      dm integrity: improve the Kconfig help text for DM_INTEGRITY
      dm cache metadata: fail operations if fail_io mode has been established
