here the helper is definitely needed, since it's called from two
places and we must make sure that prandom_init_once doesn't
duplicate its static_key in two places.
Probably makes sense to add a comment to do_once api that
do_once(func, arg);
do_once(func, arg);
is not equal to
void my_helper(void) { do_once(func, arg); }
my_helper();
my_helper();
