[GIT PULL] Ceph changes for -rc1

[Sage Weil]

Hi Linus,

Please pull the following Ceph updates from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

There are several patches from Ilya fixing RBD allocation lifecycle 
issues, a series adding a nocephx_sign_messages option (and associated bug 
fixes/cleanups), several patches from Zheng improving the (directory) 
fsync behavior, a big improvement in IO for direct-io requests when 
striping is enabled from Caifeng, and several other small fixes and 
cleanups.

Thanks!
sage
