Hi Linus,

Please pull the following Ceph updates for 2.6.36-rc1:

git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

There are a handful of bug fixes, a few of which are critical, some others
improving behavior when using a clustered MDSs. Some mount options are
also fixed, and sync_fs works a bit better (pay attention to wait flag).
The rest is fleshing out the feature set (flock/fcntl lock support,
consistency relaxation, related protocol extensions) and then lots of code
cleanup.

Thanks!
sage
