f5888750aa [DLM] sequence number missing in not_ready reply
When a status reply is sent for a lockspace that doesn't yet exist, the
message sequence number from the sender was not being copied into the
reply causing the sender to ignore the reply.

4a99c3d9d6 [DLM] reject replies to old requests
When recoveries are aborted by other recoveries we can get replies to
status or names requests that we've given up on.  This can cause problems
if we're making another request and receive an old reply.  Add a sequence
number to status/names requests and reject replies that don't match.  A
field already exists for the seq number that's used in other message
types.

e7fd41792f [DLM] The core of the DLM for GFS2/CLVM
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.
