Subject: GFS2: Fix ref count bug relating to atomic_open
From: Steven Whitehouse <[email protected]>
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.
