Not sure that does what I want. It appears to allow some 'kill' actions to wake the process. I'm sure I've looked at the 'hung task' code since 2007.

Ah, that was added in May 2015. Not surprising I didn't know about it.
I'll leave the code doing: set_current_state(signal_pending(current) ? TASK_UNINTERRUPTIBLE ? TASK_INTERRUPTIBLE); for a while longer.
