Subject[PATCH 3.10 105/123] quota: Properly return errors from dquot_writeback_dquots()
Date
3.10-stable review patch.  If anyone has any objections, please let me know.

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

From: Jan Kara <jack@suse.cz>

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.
