More fun, it would require marking them RO but leaving the dirty bit set, because this ext3 fudge where we confuse the page dirty state - or did that get fixed?
That got fixed by Nick, I think. The alternative to marking pages RO, is to walk the PTEs in MS_ASYNC, note the dirty bit and mark pages clean. But it's possibly even more complicated. Miklos
