[PATCH v3 0/3] f/madivse(DONTNEED) support

[Minchan Kim <minchan.kim@gmail.com>]

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
