No, all new symbols in 8-current go into FBSD_1.1, not 1.2. The

the MFC to 7.x would also be 1.1.1.
It is ok for a FBSD_1.1 in -current to be a superset of FBSD_1.1
in a previous branch. In fact you can't prevent them from being
different unless you mandate that all new symbols get MFC'd to
their respective namespaces in previous branches.
Perhaps I misinterpreted what you said about this last year, but I
thought you said you didn't want symbols added to existing
namespaces in -STABLE. In 7.X, why would it be okay to add new
symbols to FBSD_1.1 between releases but not to FBSD_1.0?
I think you're just off by a version. -stable didn't have
FBSD_1.1, so we just _did_ add memrchr() to a _new_ namespace
in -stable. All new and changed symbols in 8-current go
in FBSD_1.1, never in FBSD_1.0. So they can be MFC'd
in the same namespace that -current as using. After we
branched 7.0 from -current, the FBSD_1.0 namespace was
frozen. This will happen everytime we branch from -current.
