H A D | requestqueue.h | diff d4400156d415540086c34a06e5d233122d6bf56a Tue Oct 31 18:55:56 CET 2006 David Teigland <teigland@redhat.com> [DLM] fix requestqueue race
Red Hat BZ 211914
There's a race between dlm_recoverd (1) enabling locking and (2) clearing out the requestqueue, and dlm_recvd (1) checking if locking is enabled and (2) adding a message to the requestqueue. An order of recoverd(1), recvd(1), recvd(2), recoverd(2) will result in a message being left on the requestqueue. The fix is to have dlm_recvd check if dlm_recoverd has enabled locking after taking the mutex for the requestqueue and if it has processing the message instead of queueing it.
