This allows dlm_recv activity to be\nsuspended when the lockspace transitions to, from and between recovery\ncycles.\n\nThe specific bug prompting this change is one where an in-progress\nrecovery cycle is aborted by a new recovery cycle.  While dlm_recv was\nprocessing a recovery message, the recovery cycle was aborted and\ndlm_recoverd began cleaning up.  dlm_recv decremented recover_locks_count\non an rsb after dlm_recoverd had reset it to zero.  This is fixed by\nsuspending dlm_recv (taking write lock on the rwsem) before aborting the\ncurrent recovery.\n\nThe transitions to/from normal and recovery modes are simplified by using\nthis new ability to block dlm_recv.  The switch from normal to recovery\nmode means dlm_recv goes from processing locking messages, to saving them\nfor later, and vice versa.  Races are avoided by blocking dlm_recv when\nsetting the flag that switches between modes.\n\nSigned-off-by: David Teigland \u003cteigland@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"
