[PATCH] ocfs2:fix memory leak in dlm_add_migration_mle
After some parallel mount/umount test on ocfs2, we got this: slab error
in kmem_cache_destroy(): cache `o2dlm_mle': Can't free all objects.
Then we found a memleak situation in dlm_add_migration_mle().
When a mle found, it will be removed from dlm->hlist. If there is no
pointer to it at that moment, the mle will become an ?orphan mle?
that no process can find and release.

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
