Kernel 6.0-rc1 was released a few days ago. It failed to compile on the Ubuntu Mainline PPA with the old "can not fork" error.
I compiled starting with the kernel configuration from kernel 5.19.
Code:

A non relevant tangential note: Under the category "How stupid am I?":
I was helping someone on these forums or over on askubuntu with some iptables rules and totally forgot about some very restrictive rules I had installed on the same test server on which I compile the kernel. "git pull" did not work, just hanging. It took me about 20 minutes to figure out. How stupid.
