I had a look at copy_one_pte().
I cannot see any ioproc_update_page() call, not even for the COW pages.
Is it intentional?

We can live with a COW page for a considerably long time.
How could the IO-PROC. know that a process-ID / user virt. addr. pair
refers to the same page?

The comment above ioproc_update_page() says that every time when a PTE
is created / modified...

Thanks,
