Re: [PATCH 0/3] netfilter : 3 patches to boost ip_tables performance

Christoph Lameter a écrit :

It should really be do_set_mempolicy instead to be cleaner. I got a patch here that fixes the policy layer.

But still I agree with Christoph that a real vmalloc_node is better. There will be no fuzzing around with memory policies etc and its certainly better performance wise.

vmalloc_node() should be seldom used, at driver init, or when a new ip_tables is loaded. If it happens to be a performance problem, then we can optimize it.

Why should we spend days of work for a function that is yet to be used ?
