Here's a series of mostly trivial cleanups to page migration, following on from a preliminary cleanup to Documentation, and to the way rmap calls mlock_vma_page (which has to be duplicated in page migration). This started out as patch 04/24 "mm: make page migration's newpage handling more robust" in my huge tmpfs series against v3.19 in February. It was already a portmanteau then, and more has been thrown in since: not much of relevance to tmpfs, just cleanups that looked worth making. A few minor fixes on the way, nothing I think worth sending to stable. Mostly trivial, but 12/12 and a few of the others deserve some thought. Diffed against v4.3-rc6: I couldn't decide whether to use that or the v4.3-rc5-mm1 as base, but there's very little conflict anyway: 4/12 should have the second arg to page_remove_rmap() if it goes after Kirill's THP refcounting series, and 10/12 should have the TTU_FREE block inserted if it goes after Minchan's MADV_FREE series. 1/12 mm Documentation: undoc non-linear vmas 2/12 mm: rmap use pte lock not mmap_sem to set PageMlocked 3/12 mm: page migration fix PageMlocked on migrated pages 4/12 mm: rename mem_cgroup_migrate to mem_cgroup_replace_page 5/12 mm: correct a couple of page migration comments 6/12 mm: page migration use the put_new_page whenever necessary 7/12 mm: page migration trylock newpage at same level as oldpage 8/12 mm: page migration remove_migration_ptes at lock+unlock level 9/12 mm: simplify page migration's anon_vma comment and flow 10/12 mm: page migration use migration entry for swapcache too 11/12 mm: page migration avoid touching newpage until no going back 12/12 mm: migrate dirty page without clear_page_dirty_for_io etc Documentation/filesystems/proc.txt | 1 Documentation/vm/page_migration | 27 +- Documentation/vm/unevictable-lru.txt | 120 +----------- include/linux/memcontrol.h | 7 mm/balloon_compaction.c | 10 - mm/filemap.c | 2 mm/internal.h | 9 mm/memcontrol.c | 29 -- mm/migrate.c | 244 ++++++++++++------------- mm/rmap.c | 99 ++++------ mm/shmem.c | 2 11 files changed, 213 insertions(+), 337 deletions(-) Hugh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
