Subject: copy_one_pte()
Date: Tue, 13 Mar 2007 20:15:25 +0100	[thread overview]
Message-ID: <45F6F84D.20302@free.fr> (raw)

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,

Zoltan Menyhart
