[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

This is a big batch.  From Ilya we have:

 - rbd support for more than ~250 mapped devices (now uses same scheme 
   that SCSI does for device major/minor numbering)
 - crush updates for new mapping behaviors (will be needed for coming 
   erasure coding support, among other things)
 - preliminary support for tiered storage pools

There is also a big series fixing a pile cephfs bugs with clustered MDSs 
from Yan Zheng, ACL support for cephfs from Guangliang Zhao, ceph fscache 
improvements from Li Wang, improved behavior when we get ENOSPC from Josh 
Durgin, some readv/writev improvements from Majianpeng, and the usual mix 
of small cleanups.

Thanks!
sage
