I've been digging through a lot of unfamiliar code trying to figure this out on my own, and have decided it would be more efficient to see if there's an expert around. :) I'm trying to implement a kernel resource tracking/controlling system in as general a manner as possible. Essentially, for any resources that are currently held by a process, I need to know which process holds it and which processes are blocked on it. For example, if a given tty is owned by a process and three other processes are blocked waiting on it, i want to be able to track that. So, basically, my question is: are there some "central" locations in the kernel where I can place calls to my code when a process obtains a resource and when a process blocks on a resource held by another process? If so, pointers to the code (and any other thoughts) would be greatly appreciated.
