IIRC, in previous reviews we discussed this and you said you'd look at
just making those extern functions, instead of function pointers, since
realistically there's no use in being able to switch these at runtime.
What happened to that? Any particular reason not to?

Yes, I followed your suggestion that we just use functions instead of
function pointers ([17/20]).

Though we won't use pointers, we still need this structure to inform
userspace side (of LKL) to kernel. [19/20], block device
implementation uses this.
