Andrew,
Here are the mmap read-around related patches initiated by Linus. They are for linux-2.6.24-rc5-mm1. They're mainly about code cleanups. The only major new feature - auto detection and early readahead for mmap sequential reads - shows about 2% speedup on single stream case, and should perform much better in multiple streams case.
