What's in ocfs2.git

The following describes the contents of the ALL branch of

git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git

* The usual set of cleanups and fixes.
- a #include cleanup
- some nlink check fixes
- a heartbeat sector math fix

* OCFS2 now supports ext2 file attributes. Thanks to Herbert Poetzl for that
feature.

* Shared writeable mmap support. This just make use of the ->page_mkwrite()
callback to take write locks on pages. It works quite well, though there's
one unresolved issue I'd like to work out first.

* Fix mtime updates on buffered writes so that they always happen.

* An old directory readahead patch which I had never pushed upstream. IMHO,
it's actually more interesting in that it provides the code to do readahead
of other fs structures in the future.

* A patch series which removes the "dentry" vote, in favor of a locking
scheme which achieves the same thing (cluster-wide dentry delete on
unlink/rename) using fewer network messages in the average case. This
series also includes two interesting changes:
- An OCFS2 DLM API update, needed to get this going.
- A small patch to the VFS to enable a file system to manually d_move()
during rename. This also updates NFS for the behavior.

* A configfs fix - it was previously possible to create duplicate subsystem
names.

Most of this will be queued up for 2.6.19. Diffstat and shortlog are below.
