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.
