For 4 workflows:
CI
,CodeQL
,Docker build CI
andCheck Submodule Pins
, if the corresponding git ref is updated we cancel the old runs.Why cancel in general? To save resources and abandon unnecessary computation.
Why these jobs? Each of these jobs takes at least few minutes to run (considered as heavy).
Why is it safe? None of these jobs do any release or a work where cancellation might yield unexpected results. They are purely build/test/read-only jobs.
