From f4b113ae6f772b3c25fdcd73d15e9d8b17c89dcc Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 21 May 2010 19:12:51 +0200 Subject: [PATCH] reiserfs: Fix resuming of quotas on remount read-write When quota was suspended on remount-ro, finish_unfinished() will try to turn it on again (which fails) and also turns the quotas off on exit. Fix the function to check whether quotas are already on at function entry and do not turn them off in that case.
