    [PATCH] (2/3) Initial load balancing · f01419fd

    This adds a hook, sched_balance_exec(), to the exec code, to make it
    place the exec'ed task on the least loaded queue. We have less state
    to move at exec time than fork time, so this is the cheapest point
    to cross-node migrate. Experience in Dynix/PTX and testing on Linux
    has confirmed that this is the cheapest time to move tasks between nodes.
    
    It also macro-wraps changes to nr_running, to allow us to keep track of
    per-node nr_running as well. Again, no impact on non-NUMA machines.
