[GIT PULL] Ceph updates for 2.6.36-rc1

[Sage Weil]

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
