Within the kernel, yes, you can use lots of different types for the same "real" variable size, but you shouldn't, just use the well-known and common types "u8" and you will be fine. Those other ones are there due to code being brought in from all over the place, that's what happens with a codebase of 20 million lines at times :)
What's the current feeling on using typedefs to get more type safety?
typedefs are evil, never use them. No non-core-kernel developer should EVER create a new typedef, except for a function pointer signature. greg k-h
