Subject: ocfs2/dlm: fix misuse of list_move_tail() in dlm_run_purge_list()
When a lockres in purge list but is still in use, it should be moved to
the tail of purge list. dlm_thread will continue to check next lockres in
purge list. However, code list_move_tail(&dlm->purge_list,
&lockres->purge) will do *no* movements, so dlm_thread will purge the same
lockres in this loop again and again. If it is in use for a long time,
other lockres will not be processed.
