Not quite. There are actually two different time periods: 1. The time from mainline to release 2. The time from AUTOSEL email to release (1) is a superset of (2), but concerns were raised about *both* time periods being too short. Especially (1), but also (2) because reviewers can miss the 7-day review e.g. if they are on vacation for a week. Yes, they can of course miss non-AUTOSEL patches too, *if* they happen to get merged quickly enough (most kernel patches take several weeks just to get to mainline). But, AUTOSEL patches are known to be low quality submissions that really need that review. I'm glad to hear that you've increased (1) to 14 days! However, that does not address (2). It also does not feel like much of a difference, since 12 days for (1) already seemed too short. To be honest, I hesitate a bit to give you a precise suggestion, as it's liable to be used to push back on future suggestions as "this is what people agreed on before". (Just as you did in this thread, with saying 7 days had been agreed on before.) And it's not like there are any magic numbers -- we just know that the current periods seem to be too short. But, for a simple change, I think increasing (2) to 14 days would be reasonable, as that automatically gives 14 days for (1) too. If it isn't too much trouble to separate the periods, though, it would also be reasonable to choose something a bit higher for (1), like 18-21 days, and something a bit lower for (2), like 10-12 days. - Eric
