[$] Creating a healthy kernel subsystem community

Creating welcoming communities within open-source projects is a recurring
topic at conferences; those projects rely on contributions from others, so
making them welcome is important. The kernel has, rather infamously
over the years, been an oft-cited example of an unwelcoming project, though
there have been (and are) multiple efforts to change that with varying
degrees of success. Hans de Goede talked about such efforts within his
corner of the kernel project in a talk (YouTube video) at
Open
Source Summit Europe.
