[$] The 2022 embedded Linux update

A regular feature of the EmbeddedLinux Conference (ELC) has been an update on the state of embedded Linux fromconference organizer Tim Bird. It has been quite a few years since I hadthe opportunity to sit in on one, so I took one at the2022 OpenSource Summit North America (OSSNA) in Austin, Texas. OSSNA is anumbrella conference that contains ELC and a whole lot more these days.Bird gave a look at recent kernel features from an embedded perspective,talked a bit about some different technology areas and their impact onembedded Linux, andalso tried to answer a question that Andrew Morton posed in a keynote at ELC in 2008.
