[WaiLUG] userspace and kernel space memory experiment

[John]

Hi guys, I have been trying to figure out how the Linux Memory management system works,
I tried to write a small C program that is in a sleep loop waking up every 5 secs or so checking the value
of a variable (it first prints out is userspace virtual address of the variable), I then wrote a module that tries
to alter that memory location from kernel space. I have been doing this by traversing the pgd , pmd and pte arrays
and have come to the conclusion I have know Idea what I am doing :-) and idea's on how this could be done ??
