2010-10-20rbd: passing wrong variable to bvec_kunmap_irq()Dan Carpenter
We should be passing "buf" here insead of "bv". This is tricky because it's not the same as kmap() and kunmap(). GCC does warn about it if you compile on i386 with CONFIG_HIGHMEM. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>

2010-10-20block: rbd: removing unnecessary testYehuda Sadeh
rbd_get_segment() can't return a negative value, we don't need to check the return output. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net>
2010-10-20block: rbd: fixed may leaksVasiliy Kulikov
rbd_client_create() doesn't free rbdc, this leads to many leaks. seg_len in rbd_do_op() is unsigned, so (seg_len < 0) makes no sense. Also if fixed check fails then seg_name is leaked. Signed-off-by: Vasiliy Kulikov <segooon@gmail.com> Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net>
2010-10-20rbd: introduce rados block device (rbd), based on libcephYehuda Sadeh
The rados block device (rbd), based on osdblk, creates a block device that is backed by objects stored in the Ceph distributed object storage cluster. Each device consists of a single metadata object and data striped over many data objects. The rbd driver supports read-only snapshots.
