Also why not just int or u8?
Heh, because kvm_dev_ioctl_create_vm() takes an "unsigned long" for the type and
it felt wrong to store it as something else. Storing it as a smaller field should
be fine, I highly doubt we'll get to 256 types anytime soon :-)
It's the bit position. We can get only 8 types with u8 actually.
I think kvm_x86_ops.is_vm_type_supported() should take the full size though.
