If no KTAP header is found in the kernel output (e.g., because the kernel
crashed before the KUnit executor was run), it's very useful to re-run the
test with --raw_output=all, as that will show any error output (such as a
stacktrace, log message, BUG, etc). This is not particularly intuitive,
however, as --raw_output=all is not well known.
Add an extra log line to advertise --raw_output=all in this case, as it's
a terrible user experience to just get "Did any KUnit tests run?"
What's the difference to "full"?
Thanks for adding this, btw!
Normally, the --raw_output option will just pass through the actual test
results (or, rather, any kernel output from when the tests are running),
by skipping everything prior to the "KTAP version 1" line.
--raw_output=full is a synonym for --raw_output=all, which just passes
through all of the kernel output, so is useful if we never get as far as
printing that KTAP version line.
(I kept forgetting whether it was "full" or "all", which is why both are
supported.)
