Did I do wrong? More specifically, everything up to 458326ec10d1233399a342263d33878cb0afe710 lines up in next-20221220, and then I decided to rebase to squash bugfixes. Plus these are two trivial patches on top that just tweak sparse tags so 0 chance of regressions, and an also trivial security-related bugfix. > -- > MST

Did I do wrong? I am literally looking at the next-20221214 state right now, doing git log linus/master.. -- drivers/vhost/vsock.c git log linus/master.. -- drivers/vdpa/mlx5/ git log --grep="temporary variable type tweak" and seeing nothing. So none of these commits - in *any* form - were in linux-next last week as far as I can tell. Linus

Do you understand what the word "next" means? We don't call it "linux-this", do we? This is not a new rule. Things are supposed to be ready *before* the merge window (that's what makes it "next", get it?). I will also point you to to https://lore.kernel.org/lkml/CAHk-=wj_HcgFZNyZHTLJ7qC2613zphKDtLh6ndciwopZRfH0aQ@mail.gmail.com/ where I'm being pretty damn clear about things. And before you start bleating about "I needed more heads up", never mind that this isn't even a new rule, and never mind what that "next" word means, let me just point to the 6.1-rc6 notice too: https://lore.kernel.org/lkml/CAHk-=wgUZwX8Sbb8Zvm7FxWVfX6CGuE7x+E16VKoqL7Ok9vv7g@mail.gmail.com/ and if the meaning of "next" has eluded you all these years, maybe it was high time you learnt. Hmm? Linus

Hmm? > > Linus Yea I really screwed up with this one. High time I learned that "no fallout from testing" most likely does not mean "no bugs" but instead "you forgot to push to next".
