Subject: [PATCHv3 0/3] z3fold: background page compaction
Date: Thu, 27 Oct 2016 13:06:47 +0200 [thread overview]
Message-ID: <20161027130647.782b8ab1f71555200ba15605@gmail.com> (raw)
The coming patchset is another take on z3fold page layout
optimization problem. The previous solution [1] used
shrinker to solve the issue of in-page space fragmentation
but after some discussions the decision was made to rewrite
background page layout optimization using good old work
queues.
The patchset thus implements in-page compaction worker for
z3fold, preceded by some code optimizations and preparations
which, again, deserved to be separate patches.
Changes compared to v2:
- more accurate accounting of unbuddied_nr, per Dan's
comments
- various cleanups.
