Then you call make_task_dead() at the end unconditionally, and die()
becomes a noreturn function again.
No, it can return if (ret == NOTIFY_STOP), so die() is a return
function now, please see objdump -d arch/mips/kernel/traps.o.
Then should loongarch patches need to be updated, too?
Yes, I think so, will do it.
Thanks,
