I think they're about the same, really. The level of difficulty is more
in what the syscall or ioctl does and what its arguments are (ie does
QEMU have to do much mangling on the way past) rather than whether
it happens to be a syscall or an ioctl. Some syscalls are hard, but
some are trivial; same with ioctls.
