Replying to myself here: after re-readling this code again, I now think that
if hrtimer_try_to_cancel() does not fail I need a put_task_struct() to
compensate for the one that should happen in the inactive timer handler
and I just cancelled...
I do not know how I previously missed this (or maybe I just managed to
confuse myself now :)
I will check this in next week.
