Heard of my treescan program? Didn't think so. It's a highly optimised `find'. I'd like disk trace stats to help optimise treescan's access patterns.
I'd like, in decreasing order of usefulness: a summary count of accesses (reads & writes); the list of blocks looked up by the fs in order (whether they're in cache or not); timestamps; the list of block read & write requests submitted for i/o in order.
