	Actually I have a question related to this. Is it possible to find
all the aliases of a frame if you know one of the virtual addresses that
maps to it? This question is related to frames shared between processes, I
was thinking that if you have the VA for one process you could look in the
vm_area_struct and follow the shared points to find the VA's for all other
processes sharing the frame your intereste in. I know that not explained
very clearly but let me know if I'm on the right track. I'd be happy to
hope on to #kernelnewbies to discuse it with anyone with a little
time/tolerance.

	Cheers Adam
