The 5.2-rc3 kernel prepatch has been
released. “Anyway, even ignoring the SPDX changes, there’s just a
lot of small fixes spread all over, not anything that looks particularly
scary or worrisome. Maybe next week is when the other shoe drops, but maybe
this will just be a nice calm release. That would be lovely.“
