This is probably too big to be inlined, and nonblock should be a bool


It would also make sense to give end_time as a parameter, so that the
polling() code could really give a end_time for the whole duration of
poll().

(You then should test can_poll_ll(end_time) _before_ call to
ndo_ll_poll())

how would you handle a nonblocking operation in that case?
I guess if we have a socket option, then we don't need to handle none blocking any diffrent, since the user specified exactly how much time to waste polling. right?
