At present this -stable promiscuity is overriding the (sometime carefully) considered decisions of the MM developers, and that's a bit scary.
Not only scary, it is also a waste of precious time of those who carefuly evaluate stable tree backports.
I'm just as concerned with the other direction: we end up missing quite a lot of patches that are needed in practice, and no one is circling back to make sure that we have everything we need.
I took a peek at SUSE's tree to see how things work there, and looking at the very latest mm/ commit:
commit c8c7b321edcf7a7e8c22dc66e0366f72aa2390f0 Author: Michal Koutný mkoutny@suse.com Date: Tue May 4 11:12:10 2021 +0200
mm: memcontrol: fix cpuhotplug statistics flushing (bsc#1185606).
suse-commit: 3bba386a33fac144abf2507554cb21552acb16af
This seems to be commit a3d4c05a4474 ("mm: memcontrol: fix cpuhotplug statistics flushing") upstream, and I assume that it was picked because it fixed a real bug someone cares about.
I can maybe understand that at the time that the patch was written/committed it didn't seem like stable@ material and thus there was no cc to stable.
But once someone realized it needs to be backported, why weren't we told to take it into stable too?
