We cannot restart recovery. Once we begin to recover a node, keep the state of the recovery intact and follow through, regardless of any other node deaths that may occur. Signed-off-by:

If the previous master of the recovery lock dies, let calc_usage take it down completely and let the caller completely redo the dlmlock() call. Otherwise, there will never be an opportunity to re-master the lockres and recovery wont be able to progress. Signed-off-by:

Use the existing structure for blocking migrations when ASTs are pending to achieve the same result. If we can catch the assert before it goes on the wire, just cancel it and let the migration continue. Signed-off-by:

Now we never change the owner of a lock resource until unmount or node death. This will be re-enabled once some issues in the algorithm used have been resolved. Signed-off-by:

In dlmlock_remote(), do not call purge_lockres until the lock resource actually changes. otherwise, the mastery info on the lockres will go away underneath the caller. Signed-off-by:

When mastering non-recovery lock resources, additional time was frequently needed to allow the disk heartbeat to catch up with the network timeout. the recovery lock resource is time critical and avoids this path. Signed-off-by:

Recovery will spin in dlm_pre_master_reco_lockres if we do not ignore timed-out network responses from dead nodes. Signed-off-by:

Change behavior of dlm_restart_lock_mastery() when a node goes down. Dump all responses that have been collected and start over. Signed-off-by:

The OCFS2 DLM allocates a number of pages for a hash to lookup locks. There was a bug where a PAGE_SIZE bigger than the hash size (eg, 64K pages) would result in zero pages allocated. Signed-off-by:

This allows us to have a hash table greater than a single page which greatly improves dlm performance on some tests. Signed-off-by:
