Hi Linus,
Please pull the following Ceph updates from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
Alex has been busy. There are a range of rbd and libceph cleanups,
especially surrounding device setup and teardown, and a few critical fixes
in that code. There are more cleanups in the messenger code, virtual
xattrs, a fix for CRC calculation/checks, and lots of other miscellaneous
stuff.
There's a patch from Amon Ott to make inos behave a bit better on 32-bit
boxes, some decode check fixes from Xi Wang, and network throttling fix
from Jim Schutt, and a couple RBD fixes from Josh Durgin.
No new functionality, just a lot of cleanup and bug fixing.
Thanks!
sage
