Conclusion after reading a bit of everything, inotify is what I have chosen to work with. It looks very simple and does exactly what i need. Then from there i'll decide what i do next. If i wish to modify how the files are handled i would probably work something on vfs but this would really be for later! Thanks all of you who replied in this thread, you provided excellent guides for my general question. Hoping to be soon in the pool of kernel contributors as well! Thanks!
