Not sure I got your point here.

You set current to TASK_KILLABLE in the sleep loop, why do you want to change
it here to TASK_RUNNING if its about to be killed? At least in the case of
UNINTERRUPTABLE we do it merely as a redundancy after the breaking out of the
loop. Of course we also acquired the lock in the first place by that time and
we _better_ be running.
