[PATCH 0/4] md: fix lockdep warning

[Guoqing Jiang <guoqing.jiang@xxxxxxxxxxxxxxx>]

Hi,

After LOCKDEP is enabled, we can see some deadlock issues, this patchset
makes workqueue is flushed only necessary, and the last patch is a cleanup.

Thanks,
Guoqing

  md: add checkings before flush md_misc_wq
  md: add new workqueue for delete rdev
  md: don't flush workqueue unconditionally in md_open
  md: flush md_rdev_misc_wq for HOT_ADD_DISK case
  md: remove the extra line for ->hot_add_disk
