*	[DLM] fix requestqueue race	David Teigland	2006-11-30	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	[DLM] The core of the DLM for GFS2/CLVM	David Teigland	2006-01-18	1	-0/+22
	This is the core of the distributed lock manager which is required to use GFS2 as a cluster filesystem. It is also used by CLVM and can be used as a standalone lock manager independantly of either of these two projects. It implements VAX-style locking modes.
