ocfs2: sparse b-tree support
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. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
