fcc8abc8d4 [DLM] move kmap to after spin_unlock
Doing the kmap() while holding the spinlock was causing recursive spinlock
problems.  It seems the kmap was scheduling, although there was no warning
as I'd expect.  Patrick, do we need locking around the kmap?

The nodeinfo_lock rwsem needs to be initialized when the module is loaded
instead of when the dlm is first used.

Change names of local_nodeid to dlm_local_nodeid to prevent a
namespace collision. Changed other local variable to match.

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.
