I don't think pager (as in libpager) knows anything about > atime/mtime and other filesystem-specific cruft. Indeed, so pager itself doesn't handle it and it's libdiskfs that reacts to writes and updates the mtimes. > The pager knows the size; but the callbacks need to know the size too, > to decide how much to read/write in case of the last page. Yes, ext2fs apparently uses a different lock for that, alloc_lock. Samuel
