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 [2/7].
- [1/7] is to remove checkpatch's reporting in mm/swap.c
- [2/7] is to move invalidated page which is dirty/writeback on active list
into inactive list's head.
- [3/7] is to move memcg reclaimable page on inactive's tail.
- [4/7] is for moving invalidated page into inactive list's tail when the
page's writeout is completed for reclaim asap.
- [5/7] is to add profing information for evaluation.
- [6/7] is to remove zap_detail NULL dependency to some functions. It is for
next patch.
- [7/7] is to not calling mark_page_accessed in case of madvise(DONTNEED)
