It doesn't break situation 1 as the minor changes I've made to those 2 C
files should not have changed any outputted code. The change was only in
the offending parameter names.

I think good style requires that the parameter names match in the
function prototype and its declaration. Besides which if I remember
correctly the latest C++ standard does require that the parameter names
match and the next C standard might follow suit. But I think that is a
minor issue, I only updated the C files (minimally at that) to keep

I bought up a solution like this before and it was mostly argued

The kernel gods will have to give their opinion on this. Should a
"proper" fix be implemented for the offending variable names or should a
workaround be implemented. Or perhaps a combination depending on whether
the change breaks any external utilities and how bad a break that is (I say
external utilities as I can update all the files in the kernel itself). I
am inclined to think that the proper fix should be done unless something
important break in which case the ugly workaround can be used in those
limited cases. However my mind is open to be changed. After all the ugly
workaround would actually be easier for me, one Perl script.
