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: NSage Weil <sage@newdream.net>

The object will be hashed to a placement seed (ps) based on the pg_pool's hash function. This allows new hashes to be introduced into an existing object store, or selection of a hash appropriate to the objects that will be stored in a particular pool. Signed-off-by: NSage Weil <sage@newdream.net>

We were using the (weak) dcache hash function, but it was leaving lower bits consecutive for consecutive (inode) objects. We really want to make the object to pg mapping random and uniform, so use a proper hash function here. This is Robert Jenkin's public domain hash function (with some minor cleanup): http://burtleburtle.net/bob/hash/evahash.html This is a protocol revision. Signed-off-by: NSage Weil <sage@newdream.net>

These headers describe the types used to exchange messages between the Ceph client and various servers. All types are little-endian and packed. These headers are shared between the kernel and userspace, so all types are in terms of e.g. __u32. Additionally, we define a few magic values to identify the current version of the protocol(s) in use, so that discrepancies to be detected on mount. Signed-off-by: NSage Weil <sage@newdream.net>
