Good idea, I guess that we need to figure out how to do carthesian
multiplication on the different file descriptors though. Maybe we need
to treat the tst_interate_fd() as an iterator so that we can advance to
the next fd with each call, so that we can do:
struct tst_fd fd_in = {}, fd_out = {};
while (tst_iterate_fd(&fd_in)) {
while (tst_iterate_fd(&fd_out)) {
...
TST_TEST(splice(fd_in.fd, 0, fd_out.fd, 0, ...));
...
}
}
