| * | dlm: detect available userspace daemon | David Teigland | 2008-08-28 |
| | | | | | | | | | | | | | | | | 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: allow multiple lockspace creates | David Teigland | 2008-08-28 |
| | | | | | | | | | | | Add a count for lockspace create and release so that create can be called multiple times to use the lockspace from different places. Also add the new flag DLM_LSFL_NEWEXCL to create a lockspace with the previous behavior of returning -EEXIST if the lockspace already exists. Signed-off-by: David Teigland <teigland@redhat.com> | ||
| * | [DLM] dlm: user locks | David Teigland | 2006-07-13 |
| 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.
