The bugfix is two > and a half years old by now, and the bug looks real and very serious ] I've got builds ready for F30 and F31 but my local testing shows no difference in kernel build times with/without. I was hoping someone would test the rawhide build[*] and say "yup, that fixes it" in case some other even older patch is also needed. F29 just went EOL so I can't fix that one.
