Subject: memcgroup: make the memory controller more desktop responsive
From: Balbir Singh <balbir@xxxxxxxxxxxxxxxxxx>
This patch makes the memory controller more responsive on my desktop.
1. Set all cached pages as inactive. We were by default marking all pages
as active, thus forcing us to go through two passes for reclaiming pages
2. Remove congestion_wait(), since we already have that logic in
do_try_to_free_pages()
