Huh, if MODULE is defined, __devexit_p(x) evaluates to the function name
'x' itself, AFAICT.
So, if MODULE is defined and we have a reference from retained sections
to a discarded section (I'm rereading the comment over __devexit_p in
<include/linux/init.h> btw) then we'll get linker errors so we'd still
need the ifdef thing, no?
What am I missing?
