Subject: [PATCH 0/3] fix reuseaddr regression

I introduced a regression when reworking the fastreuse port stuff that allows
bind conflicts to occur once a reuseaddr socket successfully opens on an
existing tb.  The root cause is I reversed an if statement which caused us to
set the tb as if there were no owners on the socket if there were, which
obviously is not correct.

Dave I have follow up patches that will add a selftest for this case and I ran
the other reuseport related tests as well.  These need to go in pretty quickly
as it breaks kvm, I've marked them for stable.  Sorry for the regression,

Josef
