Hi, here are two patches based on memcg-aware global reclaim, which I dropped from the initial series to focus on the exclusive-lru changes. The first one is per-memcg reclaim statistics. For now, they include only pages scanned and pages reclaimed, separately for direct reclaim and kswapd, as well as separately for internal pressure or reclaim due to parental memcgs. The second one is integrating soft limit reclaim into the now memcg-aware global reclaim path. It kills a lot of code and performs better as far as I have tested it. Furthermore, Ying is working on turning soft limits into guarantees, as discussed in Prague, and this patch is also in preparation for that. Sorry for the odd point in time to submit this, I guess this will mean 3.4 at the earliest. But the soft limit removal is a bit heavy weight so it's probably easier conflict-wise to have it at the bottom of the -mm stack.
