It would seem to make perfect sense to add a 'getxattrat' syscall and allow an AT_NONBLOCK flag (which would probably be useful for statat too). The AT_NONBLOCK flag would only get attributes if they were available immediately without going to storage/network/whatever. And if it is simply a case of too many syscalls per file, then getxattrat_multi would seem to be the most general way to go.
