1. fs_epoll: try again when epoll_teardown() return 0 when poll_notify() called larger than twice when epoll_wait() blocked in the eph->sem, the semcount will be larger than 1 when epoll_wait() unblocked and will return 0 directly at the next epoll_wait. So retry to wait the eph->sem again when epoll_teardown return 0. 2. fs_epoll: poll_setup the fd again even this fd got non-expected event Some poll implementations need call poll_setup again when their internal states changed (e.g., local socket), so should add the fd to the epoll teardown list and poll_setup again at the next epoll_wait even this fd got the user non-expected event.
