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@vger, 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
