Subject: [GIT PULL] Ceph changes for 3.10
Hi Linus,
Please pull the following Ceph patches from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
This is a big pull. Most of it is culmination of Alex's work to implement
RBD image layering, which is now complete (yay!). There is also some work
from Yan to fix i_mutex behavior surrounding writes in cephfs, a sync
write fix, a fix for RBD images that get resized while they are mapped,
and a few patches from me that resolve annoying auth warnings and fix
several bugs in the ceph auth code.
Thanks!
sage
