3.11.10.2 -stable review patch. If anyone has any objections, please let me know.
------------------ 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.
