This mostly falls short answering the question "Where/when did I go
wrong?"  Personally, I think that is critical for getting good bug
reports out of normal Joes that might not really be interested in c/r
development itself.  It is like lockdep.  The guys/gals posting those
reports really don't know about kernel locking, but they are able to
improve it anyway.
