3.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Elder <[email protected]> (cherry picked from commit 7d5f24812bd182a2471cb69c1c2baf0648332e1f) In __unregister_request(), there is a call to list_del_init() referencing a request that was the subject of a call to ceph_osdc_put_request() on the previous line. This is not safe, because the request structure could have been freed by the time we reach the list_del_init(). Fix this by reversing the order of these lines.
