I took a quick peek at the code and it seems that it already initializes 
proc_fops, so maybe instead of
replacing it, you could just update it.

entry->proc_fops.mmap = ....;
that way the default handlers for seek, read and write work.

Yea the example was pretty clear and covers creating directories and 
even creating /dev entries.

It doesn't cover your specific case with mmap though.

Anyway, when you send me your code i'll be able to find out more by 
playing around.

Make sure you send me a makefile with it, because i don't know what 
flags, include paths,
and preprocessor definitions need to be sent to the compiler,
