* libceph: Fix base64-decoding when input ends in newline.Tommi Virtanen2011-03-151-1/+3
| | | | | | | | | | | It used to return -EINVAL because it thought the end was not aligned to 4 bytes. Clean up superfluous src < end test in if, the while itself guarantees that. Signed-off-by: Tommi Virtanen <tommi.virtanen@dreamhost.com> Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: factor out libceph from Ceph file systemYehuda Sadeh2010-10-201-0/+103
This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
