SubjectRe: ext2/3 performance regression in 2.6 vs 2.4 for small interleaved writes

2.4 does not have deadline scheduler. But the 2.6 deadline scheduler
is more similar to 2.4's scheduler than is the anticipatory scheduler.

Re-try 2.6 with deadline scheduler will remove some of the additional
scheduler policies that are present in the anticipatory scheduler.
