Subject: [GIT PULL] Ceph updates
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
