4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Xiaoguang <wangxg.fnst@xxxxxxxxxxxxxx>
commit 69ae5e4459e43e56f03d0987e865fbac2b05af2a upstream.
Indeed this just make the behavior similar to xfs when process has
fatal signals pending, and it'll make fstests/generic/298 happy.
