Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph updates for 3.4-rc1 from Sage Weil:
"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."
