Hi,

Just a couple of comments: I can't see any mechanism in this patch for
clearing other process's pte dirty bits when we sync a shared page (I
know you had a patch for this before), and conceptually I much prefer
to have a Dirty bit than a Clean bit, simply because that's what we
use absolutely everywhere else in the kernel.
