The new testing against 2.6.31-rc2 is ongoing. fio sync/mmap read has new behavior. I did collect some data. But suddenly with new created data, the fio_sync_read_4k regression disappeared, while fio_mmap_read is still there. Originally, the testing and bisect were stable. Let me check what happens firstly. Just update. How did you test your new readahead patches before sending to LKML?
