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. thanks -- PMM
