Now that Vladislav confirmed that it helps SCST IO performance, I'd like to push it for more -mm testing outs. I believe this will help many concurrent IO workloads, to name a few: NFS, SCST and even lighttpd. The patchset is against linux-next, after the earlier filemap and readahead cleanup/fix patches. Thanks, Fengguang --
