Another really specialized programming question, woo.
So I'm trying to figure out exactly how to go about initializing a read/write semaphore used by a few system calls I've added. I've declared the thing in my implementation file with
I've looked in the /init/main.c file and based on what I've read and seen I'm pretty sure I need to add a new function here, but I'm not sure what I need to actually set. The .h files I've looked at that define the structs use variable types I'm not familiar with and I'm really confused.

struct rw_semaphore mysemaphorebut I've been told that I need to muck around with init so the kernel doesn't just give me a bunch of garbage on startup. I have no damn clue what is involved in doing this.
