s/pool/poll/ in subject. I'm nervous about using linear search here, since we'll be growing the number of fds significantly. I think that poll_fd_woke() is inadequate in the case where a single fd has been inserted by multiple calls to poll_fd_wait(). It should presumably check for all instances and "or" their revents together. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
