Sorry, I have no crystal ball. Petr Mladek and I are working really hard
to get things in shape for mainline. I do think there is a chance for
the 6.12 merge window. But it would also need to get past Linus. Our
recent atomic console efforts were rejected [0] for the 6.11 merge
window. We are working to get that series in shape for 6.12 in parallel.
