Hello, I am following https://salsa.debian.org/carnil/linux/-/commits/5.10-stable-updates to get a current 5.10.y kernel (5.10.69 at the moment). I also hope this could be made available more officially or via optional channels to allow broader testing/usage of newer upstream versions. (On the other hand I also value the bugfixes that are done to existing versions and keeping a braod number of people on the same and thus more tested versions.)
best regards, Florian La Roche
