(from easy to more complicated): - Disable direct reclaim with 4K stacks - Do direct reclaim only on separate stacks - Add interrupt stacks to any 8K stack architectures. - Get rid of 4K stacks completely - Think about any other stackings that could give large scale recursion and find ways to run them on separate stacks too. - Long term: maybe we need 16K stacks at some point, depending on how good the VM gets. Alternative would be to stop making Linux more complicated, but that's unlikely to happen. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
