Please just send a new version with the relevant issues addressed.
The last comment clearly didn't even bother to figure out that nearly
all LTSes return -EINVAL for the combination. 5.10 and 5.15 fail as well
but are broken because apparently they didn't get the actual backport
years ago. They die in December. And upstream doesn't care about
Back-To-The-Future Frankenstein kernels.
