Subject: Relation between PFN and page block ?

Dear All,

I am trying to understand the relation between "Page Frame Number" and "Page Block".
Like how to find out if a particular page frame is associated with which page block.

I have looked into Documentation/vm/pagemap but could not understand the exact mapping.

Can somebody explain me in detail how page frame number and page block are related.

Thanks,
Pintu
