already then there is no need to send the cancel message.

a23eac99d4 ocfs2: do not modify lksb->status in the unlock ast
This can race with other ast notification, which can cause bad status values
to propagate into the unlock ast.

* prune all locks from dead nodes on $RECOVERY lock resources
* do NOT automatically add new nodes to mle nodemaps until they have properly
  joined the domain

6714d8e86b [PATCH] OCFS2: The Second Oracle Cluster Filesystem
A distributed lock manager built with the cluster file system use case
in mind. The OCFS2 dlm exposes a VMS style API, though things have
been simplified internally. The only lock levels implemented currently
are NLMODE, PRMODE and EXMODE.
