pktgen: make sure that pktgen_thread_worker has been executed
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! :pktgen:pktgen_thread_worker+0x374/0x10b0 ? autoremove_wake_function+0x0/0x40 ? _spin_unlock_irqrestore+0x42/0x80 ? :pktgen:pktgen_thread_worker+0x0/0x10b0 kthread+0x4d/0x80 child_rip+0xa/0x12 ? restore_args+0x0/0x30 ? kthread+0x0/0x80 ? child_rip+0x0/0x12 RIP list_del+0x48/0x70 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. Signed-off-by: Denis V.
