Yes, and for completeness :

accept2(int fd, ...)

pipe2(int *fds, int oflags);

eventfd2(int count, int oflags);

signalfd2(int ufd, sigset_t __user *user_mask, size_t sizemask, int oflags);

timerfd2(int ufd, int clockid, int flags,const struct itimerspec __user *utmr, int oflags) ...

We probably should name those with a better sufix than "2", it is ugly.
