3) Maintainer allows AUTOSEL, but anything picked from files/subsystems
without a stable tag requires an explicit ACK from the maintainer
for the backport.
Is new and I would be the first to opt-in:)
My rationale for #3 is that even when being careful about stable tags,
it happens that one is missing. Occasionaly AUTOSEL finds one of those
in my subsystems which I appreciate.
Does that make more sense now?
Might be a bit overbroad as it also includes x86/kvm, x86/xen, x86/pci
which I'm not that involved with, but to make it simple for you, I just
volunteered the relevant maintainers (CCed) to participate in that
experiment.
