That's not generally what we've done on Tegra. We usually keep things in
linux-next until around -rc6 to make sure whatever gets pulled into the
arm-soc tree is stable.

With what you said above I'm pretty much forced to either send you pulls
that aren't well tested (linux-next isn't supposed to get new code until
after -rc1) or I have to plan for an extra release cycle for anything
that is "big", which would mean that many new features would potentially
take 6 months to get merged.

I don't like either of those choices.
