systemtap and is it possible to figure out what is in kernel cache.

[Ranjith Ruban]

Hello

I was able to find that we can probe kernel function add_to_page_cache 
and see which process adds to kernel cache. Is there any way we can find 
out what exactly is in the cache by using systemtap like finding out the 
page address and then using crash tool . Is this possible ? Any pointers 
on this will be greatly appreciated.
