Subject: [PATCH] splitlru: memcg swapbacked pages active
Date: Saturday, June 28, 2008 - 5:22 pm

add_to_page_cache_lru puts PageSwapBacked pages on the active_anon lru,
so shouldn't mem_cgroup_charge_common mirror that by setting FLAG_ACTIVE?

Should follow mmotm's vmscan-split-lru-lists-into-anon-file-sets.patch
