Subject: [PATCH v6 0/9] bugfix of MD_CLOSING and clean up md_ioctl()

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

Changes in v6:
 - in patch 2, return directly.
 - in patch 4, return directly in case GET_DISK_INFO and GET_ARRAY_INFO.
 - in patch 7, rewrite commit message.
 - add patch 8, clean up openers check.

Changes in v5:
 - add patches 1-4 to clean up md_ioct(), pathc 4 can help us clean up
   local variable 'clear_md_closing'.
 - in patches 5 and 7, clean up local variable 'clear_md_closing'.

By the way, md_ioctl() is not readable now, I wanna to re-write it later
to make it only have one 'switch' like other drivers.

Li Nan (9):
  md: merge the check of capabilities into md_ioctl_valid()
  md: changed the switch of RAID_VERSION to if
  md: clean up invalid BUG_ON in md_ioctl
  md: return directly before setting did_set_md_closing
  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: clean up openers check in do_md_stop() and md_set_readonly()
  md: check mddev->pers before calling md_set_readonly()
