Subject: [RFC PATCH 0/5] pro-active compaction
Date: Fri, 13 Jan 2017 16:14:28 +0900 [thread overview]
Message-ID: <1484291673-2239-1-git-send-email-iamjoonsoo.kim@lge.com> (raw)
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Hello,
This is a patchset for pro-active compaction to reduce fragmentation.
It is a just RFC patchset so implementation detail isn't good.
I submit this for people who want to check the effect of pro-active
compaction.
Patch 1 ~ 4 introduces new metric for checking fragmentation. I think
that this new metric is useful to check fragmentation state
regardless of usefulness of pro-active compaction. Please let me know
if someone see that this new metric is useful. I'd like to submit it,
separately.
Any feedback is more than welcome.
Thanks.

mm/vmstat: retrieve suitable free pageblock information just once
mm/vmstat: rename variables/functions about buddyinfo
mm: introduce exponential moving average to unusable free index
mm/vmstat: introduce /proc/fraginfo to get fragmentation stat stably
mm/compaction: run the compaction whenever fragmentation ratio exceeds
the threshold
