Subject[PATCH v3 0/3] f/madivse(DONTNEED) support
Date
Recently there is a report about working set page eviction due to rsync
workload. application programmers want to use fadvise but it's not easy.
You could see detailed description on [1/3].

- [1/3] is to move invalidated page which is dirty/writeback on active list
into inactive list's head.
- [2/3] is for moving invalidated page into inactive list's tail when the
page's writeout is completed.
- [3/3] is to not calling mark_page_accessed in case of madvise(DONTNEED).

Minchan Kim (3):
deactivate invalidated pages
Reclaim invalidated page ASAP
Prevent activation of page in madvise_dontneed
