Steps to open a file/handled by kernel?

CC: all replies to: [email protected]
Hi guys, im in discussion with one of my compsci mates to start an intresting little project, its not concrete yet, not at all, i really need to get a good grasp of what im going to have to code before i decide to jump in or not, ill give you a quick run down

Basically we want to make a sort of.. auto compression/uncompression of files as there accessed/not accessed, basically to save a hell of alot of space, but before we even BEGIN to do it, i really need to understand the calls and the "arguments" and the stages the kernel/userspace (if it is invovled (if userspace is even the right word!) takes to read from a file (and write to it while we are at it)

any information people feel is relevant or any sort of url u can point me to or just a little guide of waht happens would be appreciiated, please CC: all msgs to [email protected]

Cheers
:)
