Subject: [GIT PULL] Ceph updates and RBD for 2.6.37-rc1
Hi Linus,
Please pull the following Ceph updates, refactoring, and RBD from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
The bulk of this patchset is a refactor of the Ceph file system code that
separates the network, cluster, and I/O components from the fs-specific
bits into a 'libceph' module. (This approach was requested by Christoph
at LSF in August.) Mostly this is a matter of moving files around, with a
few interface cleanups.
Another patch then implements RBD (rados block device), a network block
device backed by Ceph's distributed object store. RBD devices are
replicated, thinly provisioned, resizable, and snapshottable. The driver
is marked EXPERIMENTAL. The code has been out on -fsdevel and LKML
several times, and has been in linux-next for almost two cycles now. If
you have any lingering questions/concerns, please let me know.
Other notable patches include: switch to lock_flocks() interface to
facilitate BKL removal, a dcache_lock/i_lock locking cleanup that will
make Dave and Nick's lock scalability work a bit easier, a new ioctl to
control Ceph's striping policy on a per-directory/hierarchical basis, and
some miscellaneous non-critical cleanups.
Thanks!
sage
