Okay, thanks! > Are those things you mentioned still slated for this release? No, the three things I mentioned aren't for v5.8 (they're still under development), but sending their respective series without the -tip patches in -rc2 will result in redundant patches. (So, it's hardly the end of the world, but it's just a confusing state to be in since they appeared in -tip and then never ended up in the merge window. It'd be helpful to have them in place for things that will base their latest tree on v5.8-rc2.) -- Kees Cook
