Chris Mason 4125bf761c Btrfs: finish read pages in the order they are submitted ... The endio is done at reverse order of bio vectors. That means for a sequential read, the page first submitted will finish last in a bio. Considering we will do checksum (making cache hot) for every page, this does introduce delay (and chance to squeeze cache used soon) for pages submitted at the begining. I don't observe obvious performance difference with below patch at my simple test, but seems more natural to finish read in the order they are submitted.
