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.
