Cover letter [PATCH 0/3] context readahead for concurrent IO take 2
Andrew,
The context readahead patches have been floating around for a while. 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
