Can we please drop this thread right now.  The proposed patches are not
acceptable as-is, and everyone knows that.  The developers are going to
go off and redo things and propose a new set of patches, let's see what
the result is of that work and we can take it from there.

Random complaints about this existing patch is not useful at all
anymore, there's nothing needed to convince anyone about anything here.

thanks,

greg k-h
