    Subject[PATCH repost] sched: export sched_set/getaffinity to modules
    Author: Sridhar Samudrala <>

    sched: export sched_set/getaffinity to modules

    vhost-net driver wants to copy the affinity from the
    owner thread to thread it creates. Export
    sched_set/get affinity to modules to make this possible
    when vhost is built as a module.
