*	dlm: detect available userspace daemon	David Teigland	2008-08-28	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	If dlm_controld (the userspace daemon that controls the setup and recovery of the dlm) fails, the kernel should shut down the lockspaces in the kernel rather than leaving them running. This is detected by having dlm_controld hold a misc device open while running, and if the kernel detects a close while the daemon is still needed, it stops the lockspaces in the kernel. Knowing that the userspace daemon isn't running also allows the lockspace create/remove routines to avoid waiting on the daemon for join/leave operations.

*	[DLM] dlm: user locks	David Teigland	2006-07-13	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \|	This changes the way the dlm handles user locks. The core dlm is now aware of user locks so they can be dealt with more efficiently. There is no more dlm_device module which previously managed its own duplicate copy of every user lock.

*	[DLM] The core of the DLM for GFS2/CLVM	David Teigland	2006-01-18	1	-0/+24
	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.
