    pktgen: allow faster module unload · 551eaff1
    Eric Dumazet authored
    Unloading pktgen module needs ~6 seconds on a 64 cpus machine, to stop
    64 kthreads.
    
    Add a pktgen_exiting variable to let kernel threads die faster, so that
    kthread_stop() doesnt have to wait too long for them. This variable is
    not tested in fast path.
    
    Note : Before exiting from pktgen_thread_worker(), we must make sure
    kthread_stop() is waiting for this thread to be stopped, like its done
    in kernel/softirq.c
