    afs: Fix callback handling · 18ac6185
    David Howells authored
    In some circumstances, the callback interest pointer is NULL, so in such a
    case we can't dereference it when checking to see if the callback is
    broken.  This causes an oops in some circumstances.
    Fix this by replacing the function that worked out the aggregate break
    counter with one that actually does the comparison, and then make that
    return true (ie. broken) if there is no callback interest as yet (ie. the
    pointer is NULL).
    Fixes: 68251f0a ("afs: Fix whole-volume callback handling")
