I don't think I use dynamic_debug, but still, a pair of square brackets
doesn't make that some part of the kernel is considered to be a module,
does it? And more importantly, even if there's a difference between
"module" and "loadable module", which I rather doubt, aren't the people
who are expected to read this comment also expected to understand the
relevance of the preceding 
    #else /* MODULE */

line?
