My rule of thumb for a .c file is that if you need more than two
headers directly included by kernel.h then you should just use
kernel.h.

I have no qualms with fixing header files that include kernel.h
to include whatever it is that they need directly. That is a
worthy goal and should be enforced for all new header files.

I just don't share your enthusiasm about doing the same for .c
files.
