Yes, I am sorry but it is too late for the printk tree. I am going to
send the pull request for 6.2 today or tomorrow. Linus explicitly
asked to send the pull request early this time because the merge
window will be overlapping with the holidays.

On the positive side. There is a high chance that the changes from
the printk tree will be in the mainline early enough so that you
could manage to send this still during the merge window.
