sorry no code snippet :)

IINW a way of doing this may be by getting the process id (PID) of the 
program that opened the file and getting the relevant file name from the 
/proc/$(PID)/fd/$(FILE_DESCRIPTOR)
or in a more technical way you may use "current->files->fd[fd]" 
structure (please refer to asm/current.h and linux/sched.h )
which IMHO requires some more extra working on linux/{proc_fs.h, fs.h, 
sched.h}..
by the way i don't know exactly how you can get the filename from  the 
file descriptor :)
i'm just suggesting..
