[PATCH 3.17 265/319] quota: Properly return errors from dquot_writeback_dquots()

From: Greg Kroah-Hartman
Date: Tue Nov 11 2014 - 20:33:43 EST


3.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jan Kara <jack@xxxxxxx>

commit 474d2605d119479e5aa050f738632e63589d4bb5 upstream.

Due to a switched left and right side of an assignment,
dquot_writeback_dquots() never returned error. This could result in
errors during quota writeback to not be reported to userspace properly.
Fix it.
