OK, this was a pain because the error did not show up until late in
the day (something in Andrew's patch series exposed the problem - note
my report was sent at 9:09 PM - my day starts about 7:30 AM). This is
after I had merged maybe 150-200 tress in top of yours. My choices are
few at that point (you don't expect me to remerge all those trees,
right?). Almost all errors I see are immediately after I merge a tree,
at which point my usual response is to reset my tree to before the
merge and then merge the previous day's version of the tree. Generally,
I do not fix build errors unless they are caused by an interaction
between 2 trees.

Given that I had spent some time to figure out what the problem was, I
expected a fix to be done pretty soon, so the easiest way I could
continue was to just mark btrfs broken and continue on (I still had
another hour to go before I was finished (my days get really long just
before Linus does a release :-( ).
