      pktgen: make sure that pktgen_thread_worker has been executed · d3ede327
      Denis V. Lunev authored
      The following courruption can happen during pktgen stop:
      list_del corruption. prev->next should be ffff81007e8a5e70, but was 6b6b6b6b6b6b6b6b
      kernel BUG at lib/list_debug.c:67!

      The problem is that pktgen_thread_worker can not be executed if kthread_stop
      has been called too early. Insert a completion on the normal initialization
      path to make sure that pktgen_thread_worker will gain the control for sure.
