They can (not immediately sure how though?), but they don't with the exception of the few that don't tag at all and send you patches in bundles. I mean, that's what the huge thread about the stable trees that hopefully leads to a conversation at KS is about, right? > And, given the huge number of patches for stable that come in during > the -rc1 merge window, there's no way I can get to them all before -rc2 > comes out, so this will probably end up being the case for most of them > anyway. Sheer numbers forcing some to be pushed out isn't really that great when the problem is spread across the whole window. I'm not saying you aren't correct that a lot of them don't get pushed to stable releases until post -rc2, but at that point you're playing catch up. I was suggesting just sitting on them until -rc2 entirely. Basically, don't release a stable kernel until the next version is at -rc2. Let me phrase this as a question instead. Is there something we can do to help catch the patches that get sucked into stable during the merge window and then wind up causing issues and reverted/fixed after things settle down in the -rc releases? Reviewing the patches submitted for those stable kernels isn't necessarily sufficient, since the issues I'm concerned about aren't spotted until after the release anyway. It's a two-fold problem. The first is one we're never going to fix in that people are human and make mistakes and sometimes patches don't get tested well enough before they're tagged for stable. The second issue is a combination of timing and volume. I doubt we're going to fix the volume since we keep touting the increasing change rate as a sign of success, but could we fix the timing by forcing things to bake more in the -rc releases? I'm offering to help in whatever way you think is best. It's your workflow (and sanity) that are the most impacted. However, I share the pain whenever something breaks in stable through the wonderful place that is Fedora bugzilla so I'm looking for ways to reduce that. josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
