From: Andi Kleen<ak@xxxxxxxxxxxxxxx> Apply the rmap chain lock batching to anon_vma_unlink() too. This speeds up exit() on process chains with many processes, when there is a lot of sharing. Unfortunately this doesn't fix all lock contention -- file vmas have a mapping lock that is also a problem. And even existing anon_vmas still contend. But it's better than before.
