[PATCH v20 05/20] mm/thp: Simplify lru_add_page_tail()

Simplify lru_add_page_tail(), there are actually only two cases possible: split_huge_page_to_list(), with list supplied and head isolated from lru by its caller; or split_huge_page(), with NULL list and head on lru - because when head is racily isolated from lru, the isolator's reference will stop

[PATCH v20 02/20] mm/memcg: bail early from swap accounting if memcg disabled

[PATCH v20 17/20] mm/swap.c: serialize memcg changes in pagevec_lru_move_fn

Hugh Dickins' found a memcg change bug on original version: If we want to change the pgdat->lru_lock to memcg's lruvec lock, we have to serialize mem_cgroup_move_account during pagevec_lru_move_fn. The possible bad scenario would like: cpu 0 cpu 1 lruvec

[PATCH v20 16/20] mm/compaction: do page isolation first in compaction

Currently, compaction would get the lru_lock and then do page isolation which works fine with pgdat->lru_lock, since any page isoltion would compete for the lru_lock. If we want to change to memcg lru_lock, we have to isolate the page before getting lru_lock, thus isoltion would block page's memcg

[PATCH v20 12/20] mm/vmscan: remove lruvec reget in move_pages_to_lru

[PATCH v20 18/20] mm/lru: replace pgdat lru_lock with lruvec lock

This patch moves per node lru_lock into lruvec, thus bring a lru_lock for each of memcg per node. So on a large machine, each of memcg don't have to suffer from per node pgdat->lru_lock competition. They could go fast with their self lru_lock. After move memcg charge before lru inserting, page

[PATCH v20 06/20] mm/thp: narrow lru locking

lru_lock and page cache xa_lock have no obvious reason to be taken one way round or the other: until now, lru_lock has been taken before page cache xa_lock, when splitting a THP; but nothing else takes them together. Reverse that ordering: let's narrow the lru locking - but leave

[PATCH v20 08/20] mm: page_idle_get_page() does not need lru_lock

From: Hugh Dickins It is necessary for page_idle_get_page() to recheck PageLRU() after get_page_unless_zero(), but holding lru_lock around that serves no useful purpose, and adds to lru_lock contention: delete it. See https://lore.kernel.org/lkml/20150504031722.GA2768@blaptop for the discussion
