There are 2 signals to tell dpc_thread to terminate (UNLOADING\nflag and kthread_stop).\n\nOn setting the UNLOADING flag when dpc_thread happens to run at the time\nand sees the flag, this causes dpc_thread to exit and clean up\nitself. When kthread_stop is called for final cleanup, this causes use\nafter free.\n\nRemove UNLOADING signal to terminate dpc_thread.
