SubjectRe: [RFC 3/6] Make nr_pagecache a per zone counter
> By the way, why does nr_pagecache needs to be an atomic variable on UP systems?

At least on X86 UP atomic doesn't use the LOCK prefix and is thus quite
cheap. I would expect other architectures who care about UP performance
(= not IA64) to be similar.
