From 08261673cb6dc638c39f44d69b76fffb57b92a8b Mon Sep 17 00:00:00 2001 From: Andrew Perepechko Date: Mon, 12 Apr 2010 22:16:50 +0400 Subject: [PATCH] quota: Fix possible dq_flags corruption dq_flags are modified non-atomically in do_set_dqblk via __set_bit calls and atomically for example in mark_dquot_dirty or clear_dquot_dirty. Hence a change done by an atomic operation can be overwritten by a change done by a non-atomic one. Fix the problem by using atomic bitops even in do_set_dqblk.
