Welcome to the world of kernel hacking and speaking the 'truth' and being 'honest'
does have it's benefits as you will see soon :)

Go through the link below very carefully, you do not require two modules. One single module
that intercepts a syscall and does what you have to do.. please do pay careful attention to the comments
within the code!
So it's a programming test to get a job? That's worse than trying to
cheat on an exam, as it would mean that I pass the test, not you :(
Though I agree 110% with gregkh 'I' also have been where Ajinkya is coming from so many times.
I have been there, done that too many times to walk away now so.. I understand the man's pain and frustration.
So against my better judgement I have given him something if he studies carefully will help him to do what its is he must.
good luck!

Greg, he told us the plain truth and all he wants is some guidance. If I am out of line you can bust me as usual on IRC ! How is telling the simple and plain 'truth' equate to 'cheating" ? Duhh...
Good luck, hope this helps - Aruna
