[PATCH 4.19 144/422] f2fs: submit bio after shutdown

From: Greg Kroah-Hartman
Date: Tue Nov 19 2019 - 00:31:51 EST


From: Jaegeuk Kim <jaegeuk@xxxxxxxxxx>

[ Upstream commit 5ce805869cbed93267ed26552ff76e30f05c91f7 ]

Sometimes, some merged IOs could get a chance to be submitted, resulting in
system hang in shutdown test. This issues IOs all the time after shutdown.
