Subject: [GIT PULL] Ceph updates for -rc1
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
