Subject: [PATCH v4 0/4]  md: Don't clear MD_CLOSING when the raid is about to stop

From: Li Nan <linan122@...wei.com>

Changes in v4:
 - insert 'break;' to avoid fall-through in patch 3.

Changes in v3:
 - rename vaires 'did_set_md_closing' in patch 1.
 - rename function mddev_set_closing_and_sync_blockdev() in patch 2.
 - reorganize conditions in patch 3.
 - add a new patch to clean up md_set_readonly().

Changes in v2:
 - don't clear MD_CLOSING in md_clean().
 - set MD_CLOSING and sync blockdev in array_state_store().

Li Nan (4):
  md: Don't clear MD_CLOSING when the raid is about to stop
  md: factor out a helper to sync mddev
  md: sync blockdev before stopping raid or setting readonly
  md: check mddev->pers before calling md_set_readonly()
