My guess is that since we don't have stdin/out/err fds then,
theoretically, something like this can happen
int main()
{
...
int fd = open(.... );
int fd = open(..., "vfat.ko");
//fd is 1
fprintf(stdout, "loading vfat\n");
...
}
stdout (fd 1) is not stdout, it's fd that we got from open(vfat.ko).
Does this make sense?
