[DLM] dump rsb and locks on assert

2006-08-21T13:50:09Z

Introduce new function dlm_dump_rsb() to call within assertions instead of dlm_print_rsb(). The new function dumps info about all locks on the rsb in addition to rsb details. Signed-off-by: David Teigland Signed-off-by: Steven Whitehouse

[DLM] dlm: user locks

2006-07-13T13:25:34Z

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. Signed-off-by: Patrick Caulfield Signed-off-by: David Teigland Signed-off-by: Steven Whitehouse

[DLM] fix grant_after_purge softlockup

2006-05-02T17:34:03Z

In dlm_grant_after_purge() we were holding a hash table read_lock while calling put_rsb() which potentially removes the rsb from the hash table, taking the same lock in write. Fix this by flagging rsb's ahead of time that have been purged. Then iteratively read_lock the hash table, find a flagged rsb, unlock, process rsb.

[DLM] The core of the DLM for GFS2/CLVM

2006-01-18T09:30:29Z

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.
