So far, I can only reproduce this as a root user and then also need to Ctrl-C the reproducer in order for the kernel to stuck in request_wait_answer() forever probably because no response from the server (the server was already exited). > > IMPORTANT: if you fix the issue, please add the following tag to the commit: > Reported-by: syzbot+ea48ca29949b1820e745@xxxxxxxxxxxxxxxxxxxxxxxxx > > INFO:
