Dear friends,

I have a very simple question related to pages.

Suppose, I have a kernel virtual address. Can I know which is the process that last used this address?

Probably we might need to look at the members of the page strucre which the virtual address is part of. Any relevant information will be very helpful.

PS: I have crash tool to debug the issue.

Regards,

Manty
