Actually all four lines do that. The first two for a write access on a present, read-only pte, the other two for a write on a non-present pte. > we should update the file time when it is marked > clean, and "msync(MS_SYNC)" should update it as part of *that*. That would need a new page flag (PG_mmap_dirty?). Do we have one available?
