    ocfs2: sparse b-tree support · dcd0538f
    Mark Fasheh authored
    Introduce tree rotations into the b-tree code. This will allow ocfs2 to
    support sparse files. Much of the added code is designed to be generic (in
    the ocfs2 sense) so that it can later be re-used to implement large
    extended attributes.
    This patch only adds the rotation code and does minimal updates to callers
    of the extent api.
