Given that the kernel keeps seeing more and more lines of code in each new release, tools around the kernel keep evolving (new fuzzers, testing suites, etc), and code gets more eyes, this guarantees that you'll see more and more stable patches for each release as well. Is there a reason not to take LED fixes if they fix a bug and don't cause a regression? Sure, we can draw some arbitrary line, maybe designate some subsystems that are more "important" than others, but what's the point?=
