This series is the only remaining blocker to finalize the infrastructure
cleanup.
Therefore, may I kindly ask if we could get this merged, so that I can prepare
and (re)submit the last part of the original (large) series?
The only patches that haven't been reviewed/acked yet are 7 and 8. Those are not
critical, and I'd rather send them separately (together with patch 9) if that
would let us move forward sooner.
Thanks,
Cristian
