[GIT PULL] Ceph updates

[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

The biggest chunk is a series of patches from Ilya that add support for 
new Ceph osd and crush map features, including some new tunables, primary 
affinity, and the new encoding that is needed for erasure coding support.  
This brings things into parity with the server side and the looming 
firefly release.  There is also support for allocation hints in RBD that 
help limit fragmentation on the server side.

There is also a series of patches from Zheng fixing NFS reexport, 
directory fragmentation support, flock vs fnctl behavior, and some issues 
with clustered MDS.

Finally, there are some miscellaneous fixes from Yunchuan Wen for 
fscache, Fabian Frederick for ACLs, and from me for fsync(dirfd) 
behavior.

Thanks-
sage
