Subject: [PATCH 0/5] md: fix/prevent dm-raid regressions

From: Yu Kuai <yukuai3@...wei.com>

There are some problems that we fixed in md/raid, and some apis is changed.
However, dm-raid rely the old apis(noted that old apis is problematic in
corner cases), and now there are regressions in lvm2 testsuite.

This patchset fix some regressions(patch 1-3), and revert changes to
prevent regressions(patch 4,5). Noted that the problems in patch 4,5 is
not clear yet, and I'm not able to locate the root cause ASAP, hence I
decide to revert changes to prevent regressions first.

Yu Kuai (5):
  md: don't ignore suspended array in md_check_recovery()
  md: don't ignore read-only array in md_check_recovery()
  md: make sure md_do_sync() will set MD_RECOVERY_DONE
  md: revert commit fa2bbff7b0b4 ("md: synchronize flush io with array
    reconfiguration") for dm-raid
  md: use md_reap_sync_thread() directly for dm-raid
