    SubjectRe: [PATCH] Cpuset: rcu optimization of page alloc hook
    > Thanks to Andi Kleen and Nick Piggin for the suggestion.

    Thanks. But i guess it would be still a good idea to turn
    ia "check that there is no cpuset" test into an inline
    so that it can be done without a function call. Only when
    it fails call the out of line cpuset full checking function.

    This would make the common case of a kernel with cpuset
    compiled in but nobody using it faster.

    This could be done even without any memory barriers of
    any kind.
