[PATCH RFC v0 0/6] mm: proof-of-concept memory compaction without isolation

[Konstantin Khlebnikov <koct9i@gmail.com>]

This is incomplete implementation of non-isolating memory migration and
compaction. It's alive!

The main reason -- it can preserve lru order during compaction.


Also it makes implementation of migration for various types of pages: zram,
balloon, ptes, kernel stacks [ Why not? I've already migrated them accidentally
and kernel have crashed in very funny places ] much easier: owner just have to
set page->mappingw with valid method a_ops->migratepage.

Konstantin Khlebnikov (6):
      pagevec: segmented page vectors
      mm/migrate: move putback of old page out of unmap_and_move
      mm/cma: repalce reclaim_clean_pages_from_list with try_to_reclaim_page
      mm/migrate: page migration without page isolation
      mm/compaction: use migration without isolation
      mm/migrate: preserve lru order if possible
