Thank you for your answer. You write "if you use
multithreading (a good idea)" , is it a good idea to protect variable access
with a mutex (it's always when using threads) or is it a good idea to use
multi threading in the fs implementation? In the second case, why, what,
how?

I believe Fuse is going to be a great tool to do what I want to. I need to
embed a perl interpreter into the fs to run some commands when a file is
modified. I wonder if it would have been possible to do that in a kernel
module.

Cheers, Nadim.
