It was sent as a fix to Linus. Dunno, 120 lines of new code? Even if it's okay for an rc, I don't see why it is would be backported to stable releases and release it without any kind of testing. Maybe for 5.9 the chances of breaking things are low, but stuff like locking rules might have changed since older releases like 5.4 or 4.19. The autoselection bot does not know that, it basically crosses fingers that these larger-scale changes cause the patches not to apply or compile anymore. Maybe it's just me, but the whole "autoselect stable patches" and release them is very suspicious. You are basically crossing fingers and are ready to release any kind of untested crap, because you do not trust maintainers of marking stable patches right. Only then, when a backport is broken, it's maintainers who get the blame and have to fix it. Personally I don't care because I have asked you to opt KVM out of autoselection, but this is the opposite of what Greg brags about when he touts the virtues of the upstream stable process over vendor kernels.
