[$] Next steps for kernel workflow improvement

The kernel project's email-based development process is well establishedand has some strong defenders, but it isalso showing its age. At the 2019 KernelMaintainers Summit, it became clear that the kernel's processes aremuch in need of updating, and that the maintainers are beginning tounderstand that. It is one thing, though, to establish goals for animproved process; it is another to actually implement that process andconvince developers to use it. At the 2019Open Source Summit Europe, a group of 20 or so maintainers anddevelopers met in the corner of a noisy exhibition hall to try to work out what some ofthe first steps in that direction might be.
