Convert mle list to a hash
These patches convert the mle list to a hash. The same patches apply on
ocfs2 1.4 too.
Currently, we use the same number of hash pages for mles and lockres'.
This will be addressed in a future patch that will make both of them
configurable.

o2dlm mle hash patches - round 2
The changes from the last drop are:
1. Patch 11 removes struct dlm_lock_name.
2. Patch 12 is an unrelated bugfix. Actually is related to a bugfix
that we are retracting in mainline currently. The patch may need more testing.
While I did hit the condition in my testing, Marcos hasn't. I am sending it
because it can be queued for 2.6.30. Give us more time to test.
3. Patch 13 will be useful

[git patches] Ocfs2 updates for 2.6.30
Hi,
The following patches comprise the bulk of Ocfs2 updates for the
2.6.30 merge window. Aside from larger, more involved fixes, we're adding
the following features, which I will describe in the order their patches are
mailed.
Sunil's exported some more state to our debugfs files, and
consolidated some other aspects of our debugfs infrastructure. This will
further aid us in debugging

[PATCH 0/62] Ocfs2 updates for 2.6.26-rc1
The following series of patches comprises the bulk of our outstanding
changes for Ocfs2.
Aside from the usual set of cleanups and fixes that were inappropriate for
2.6.25, there are a few highlights:
The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location
meshes better with modern sysfs layout. A symbolic link has been placed in
the old location so as to
