  • open(2) must always include one of O_RDONLY, O_WRONLY, or O_RDWR. No need
    for any O_APPEND special case.

    Passing O_WRONLY|O_RDWR is undefined according to the man page, but the
    Linux VFS interprets this as O_RDWR, so we'll do the same.

    This fixes open(2) with flags O_RDWR|O_APPEND, which was incorrectly being
    translated to readonly.

  • 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.
