Dan Carpenter	b8d0638a98	rbd: null vs ERR_PTR ... ceph_alloc_page_vector() returns ERR_PTR(-ENOMEM) on errors. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>	2010-10-20 15:38:24 -07:00
Yehuda Sadeh	f4cf3deef4	block: rbd: removing unnecessary test ... 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>	2010-10-20 15:38:20 -07:00
Vasiliy Kulikov	28f259b7cd	block: rbd: fixed may leaks ... 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>	2010-10-20 15:38:19 -07:00
Yehuda Sadeh	602adf4002	rbd: introduce rados block device (rbd), based on libceph ... 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.
