Subject: [GIT PULL] Ceph updates for 3.12 (take 2)

Hi Linus,

Please pull the following Ceph updates from

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

This includes both the first pile of Ceph patches (which I sent to 
torvalds@...r, sigh) and a few new patches that add support for fscache 
for Ceph.  That includes a few fscache core fixes that David Howells asked 
go through the Ceph tree.  (Thanks go to Milosz Tanski for putting this 
feature together.)

This first batch of patches (included here) had (has) several important 
RBD bug fixes, hole punch support, several different cleanups in the page 
cache interactions, improvements in the truncate code (new truncate mutex 
to avoid shenanigans with i_mutex), and a series of fixes in the 
synchronous striping read/write code.  On top of that is a random 
collection of small fixes all across the tree (error code checks and error 
path cleanup, obsolete wq flags, etc.).

Thanks!
sage
