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
