    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.
