Look, this is not going well.


You specifically said in your first patchset you considered the type2 
support patchset complete but too large or complex, so you were taking 
parts of it as a prelude for making it easier to review/accept. Just 
face that and not twist the argument.


FWIW, I'm against you doing so because:


1) You should have commented in the type2 patchset about your concern, 
and gave advice about doing such a prelude (by me) or offer yourself for 
doing it.

2) Just following your approach, anyone could do the same for any 
patchset sent to the list. This is not a good precedent.

3) If this is going to be allowed/approved, I'm not going to be 
comfortable within this community. If it is just me, I guess it will not 
be a big loss.


None has commented yet except you and me, what I do not know if it is 
because this is a nasty discussion they do not want to get entangle 
with, or because they just think your approach is OK. If not further 
comment and your patchset is accepted, nothing else will be needed to say.
