We never send out these FAILED emails to the mailing lists, as that would make just even more noise. It's always been this way, sorry. > Second, the upstream commit cherry-picks to 6.1, 5.15, and 5.10 without > conflict.

This has always been the case in the decades we have been running the stable kernels :) thanks, greg k-h
