[$] Bash the kernel maintainers

Laurent Pinchart ran a session at the 2017 Embedded Linux Conference Europeentitled "Bash the kernel maintainers"; the idea was to get feedback fromdevelopers on their experience working with the kernel community. A fewdays later, the Maintainers Summit held a free-flowing discussion on theissues that were brought up in that session. Some changes may result fromthis discussion, but it also showed how hard it can be to change how kernelsubsystem maintainers work.
