Next: [PATCH 8/8] rbd: introduce rados block device (rbd), based on libceph
From: Sage Weil on 13 Aug 2010 13:50
Hi,

The rados block device (rbd) implements a network block device backed by
the Ceph distributed object store (think nbd/iSCSI, but distributed and
fault tolerant). At the suggestion of Christoph and James, this version
of the patchset factors out the common Ceph bits (the network protocol,
cluster membership, and object storage parts) into a libceph module
(currently in net/ceph/ and include/linux/ceph/) that is shared by the
file system component (fs/ceph) and rbd (drivers/block/rbd.c). The first
few patches lay some groundwork, #7 moves does the ceph -> libceph+ceph
split, and #8 adds the block device driver.

The block device code has been in linux-next for a while, but it could
use some review by someone more familiar with the block layer. The rbd
code is originally based on osdblk, and has a similar sysfs interface
(rbd also supports snapshots, so there are a few more knobs for that).

Two questions --

1- Are net/ceph/ and include/linux/ceph/ appropriate locations for the
libceph code? (It seemed more similar to other net/ residents than the
stuff in lib/.)

2- Do I need an explicit ACK from any block people before sending this
to Linus? Carrying/rebasing the refactoring patch out of tree will be
tedious, so I would like to push it sooner rather than later.

Thanks!
sage

PS This code is also available in git at

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