2012-05-07crush: use a temporary variable to simplify crush_do_ruleSage Weil
Use a temporary variable here to avoid repeated array lookups and clean up the code a bit. This reflects ceph.git commit 6b5be27634ad307b471a5bf0db85c4f5c834885f. Reviewed-by: Alex Elder <elder@inktank.com> Signed-off-by: Sage Weil <sage@inktank.com>
2012-05-07crush: be more tolerant of nonsensical crush mapsSage Weil
If we get a map that doesn't make sense, error out or ignore the badness instead of BUGging out.

2010-10-20ceph: factor out libceph from Ceph file systemYehuda Sadeh
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>
