This is a note to let you know that I have just added a patch titled GFS2: Fix ref count bug relating to atomic_open to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From d390891d3763258b69303fb33a57d289ce4323f8 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse <swhiteho@redhat.com> Date: Thu, 21 Nov 2013 18:47:57 +0000 Subject: GFS2: Fix ref count bug relating to atomic_open commit ea0341e071527d5cec350917b01ab901af09d758 upstream. In the case that atomic_open calls finish_no_open() with the dentry that was supplied to gfs2_atomic_open() an extra reference count is required. This patch fixes that issue preventing a bug trap triggering at umount time.
