[GIT PULL] Ceph updates for -rc1

[Sage Weil]

Hi Linus,

Please pull the following Ceph updates from

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

We have a pile of bug fixes from Ilya, including a few patches that sync 
up the CRUSH code with the latest from userspace.  There is also a long 
series from Zheng that fixes various issues with snapshots, inline data, 
and directory fsync, some simplification and improvement in the cap 
release code, and a rework of the caching of directory contents.  To top 
it off there are a few small fixes and cleanups from Benoit and Hong.

Thanks!
sage
