I am working on distributed shared memory under linux 2.0.32, and I have the following problem: How do I synchronize pages shared by two processes. This problem is equivalent to swapping shared pages. When I want to swap a shared page out, how can I find all the ptes in all processes which share it?
Here's a scenario illustrating what I want to do: two processes (A and B) share a page of memory with a remote process R. 1) R writes to the shared page and tells A 2) A needs to invalidate its pte which references the page and B's pte. 3) Question: how does A find B's pte which references the page?
TIA --Noel
