I'd need to look at the current tree, and then trace backwards through all 60,000 changesets to see which ones had actual changes to this file. Could you expand the tuple in the tree object to include a back pointer to the previous tree in which the tuple changed? Or does adding history to the tree violate other goals of the tree type? -Tony - 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/
