:    Ugh, I must have broken something in the putpages code.  I'll look
:    into it.

    I think I muffed up putpages when I tried to fix msdosfs. I thought
    the pages were busied but it looks like they aren't busied.  In fact,
    it looks like the caller already properly soft-busies the pages so
    I dont need to do that either.

    Tell me if this patch works.
