I'm fine with having this backported.
Thanks. I can send the cherrypicks your way. Do you recommend that I include the three follow-up fixes though?
c14376de3a1b printk: Wake klogd when passing console_lock owner fd5f7cde1b85 printk: Never set console_may_schedule in console_trylock() c162d5b4338d printk: Hide console waiter logic into helpers dbdda842fe96 printk: Add console owner and waiter logic to load balance console writes
Maybe it'll also make sense to make the reproducer into a test that can go under tools/testing/ and we can backport that as well? It'll be helpful to have a way to make sure things are sane.
