James,
You seem to be asking about the use of the standard C keywords /
tokens: static, inline, and void associated with a function
declaration.
If so, any semi-advanced book on the C programming language should be
able to address your questions thoroughly. You should not need to
find a kernel specific book. In fact, most linux kernel books will
not address questions related to core C language constructs such as
those.
My basic advice is you should become proficient with the C language as
a user space programmer before delving into the kernel. Many places
in the kernel use advance C constructs which even advanced user space
C programmers find hard to grasp. Questions about those types of
usage are very appropriate for this list and will often be better
addressed in kernel specific books I believe.
Good Luck
Greg
