Every one of these asks adds friction for patch authors. For code that has already shipped in a Linus release it's a reasonable ask, but... > I am not looking for a fight.

This is a fix for a new ondisk feature that landed in 5.19-rc1. The feature is EXPERIMENTAL, which means that it **should not** be backported to 5.18, 5.15, or any other LTS kernel. New features do NOT fit the criteria for LTS backports.

This fix **WILL NOT APPLY** to 5.18! --D > Thanks, > Amir.
