It defers readahead when the laptop is spinned down, which may cause unpleasant delays if the user is watching movie and the media player do not cache enough data in userland. readahead-nfsd-case-remove-ra_min.patch ======================================= Please fold it immediately to avoid a compile error when bisecting. readahead-insert-cond_resched-calls.patch readahead-remove-size-limit-on-read_ahead_kb.patch readahead-remove-size-limit-of-max_sectors_kb-on-read_ahead_kb.patch ==================================================================== It may be better to push them to mainline _before_ the other patches. They solve some issues on large readahead size. The main users are currently some laptop mode users.
