I wrote some functions for file handling in kernel module. 
Check the source : http://linuxkernel.to/klib/klib/src/fileio.c
(The basic idea is from khttpd)

This is part of my personal klib (kernel library) project. 
You can download the full source : http://klib.sourceforge.net/download/klib.tar.gz
