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?
If the thread already spent 50us in the poll() system call, it for sure should not call any ndo_ll_poll(). This makes no more sense at this point. ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
