EXPORT_SYMBOL(pidhash) or something. Make sure you included sched.h

I'm afraid there's only so much help that can be given. Some effort may
be required on your part to make this work. Help with basic concepts
and Linux conventions is more likely to be found on irc.openprojects.net
#kernelnewbies or the kernelnewbies@nl.linux.org mailing list.
Cheers,
