Yes, I see thats sort of problematic.
I try to keep the srcrevs uptodate but this may not work all the time
especially with release branches. One option to have is to use AUTOREV
but I do not like that option
as much either but it would be good to have a dev kernel in layer too
so we know any issues impacting us
early on and new features which depend on latest kernels e.g. vcgraphics
I am fine to carry it locally, or may be we can have a bleeding branch
to have these sort of stuff
