I was relying on definitions like this: B*-tree (data structure) Definition: A B-tree in which nodes are kept 2/3 full by redistributing keys to fill two child nodes, then splitting them into three nodes. To tell the truth, I haven't read your code that closely, sorry, but I got the impression that you're doing rotations for balancing no? If not then have you really got a b*tree? -- Daniel - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
