For 'hhx' is probably does make sense in some cases.

That said, for kernel work, if you work on byte values, I would
seriously suggest not using 'char' at all, which has badly defined
sign.

And 'signed char' makes no sense either.

So while 'hhx' makes sense in the general case, for kernel work I'd
much rather see "don't use stupid types".

So why not just use 'unsigned char' (or 'u8' if you think typing is boring).
