I saw no warnings at all when I did the grep.  The only ouput from grep
was the name of the file.

Must be something weird on your machine.

It generally isn't relevant where a function is located.  Man pages
are supposed to document the required syntax and not the layout of
the source tree, which can change at any time.

FreeBSD has generally excellent man pages for kernel functions.  Linux,
on the other hand, has virtually no kernel documentation at all, so the
only way to figure out how a routine works is to examine the code.

I can speak authoritatively on this because I make my living developing
drivers for Linux.
