no of course it doesn't.... But I too am confused about Dave's assertion that it only reflects ondisk state when we have that pesky delalloc flag. Whose idea was that, anyway? ;) I'd certainly buy the argument that it -should- only reflect ondisk state, and we should nuke the delalloc flag from orbit, if we could, though. -Eric
