Subject: [PATCH 0/2] md: flush deadlock bugfix

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

I recently identified a flush deadlock issue, which can be resolved
by this patch set. After testing for a day in an environment where the
problem can be easily reproduced, I did not encounter the issue again.

Before a complete overwrite of the md flush, first fix the issue with
this patch set.

Li Nan (2):
  md: change the return value type of md_write_start to void
  md: fix deadlock between mddev_suspend and flush bio
