I'm not going to apply this as long as it plays experimental games with "shrink_icache()" and friends. I haven't seen anybody comment on the performance on this, and I can well imagine that it would potentially shrink the dcache too aggressively when there are lots of inactive-dirty pages around, where page_launder is the right thing to do, and shrinking icache/dcache might not be.
I'd really like to avoid having the MM stuff fluctuate too much. Have people tested this under different loads etc?
