If there's an ext4 bug, why haven't you reported it to the linux-ext4 list? I've done a Google search for "Steigerwald ext4 readahead" and I can't find any bug report related to kernel oops that are ext4/readahead-related. No one else has reported such a bug to me, and I run a complete set of regression tests before I push ext4 changes to Linus. So I'm not sure what you're seeing. But complaining about it in passing on an e-mail without sending a formal bug report to the linux-ext4 mailing list is not likely to solve your problem... - Ted
