Message-ID: <20101122175229.GC5512@lsanfilippo.unix.rd.tt.avira.com> Date: Mon, 22 Nov 2010 18:52:29 +0100 From: Lino Sanfilippo <LinoSanfilippo@....de> To: eparis@...hat.com Cc: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org Subject: [PATCH] fanotify: dont destroy mark when ignore mask is cleared In mark_remove_from_mask() the mark is destroyed regardless of whether the event mask or ignore mask is cleared. We should only destroy the mark if the event mask is cleared.
