In PRs, it is incorrect to use the last commit sha as a cache tag for a docker kernel image.
By default, on
pull_request
,actions/checkout
pulls a fake merge commit (PR into the default branch), and potentially an outdated kernel image from the cache might be used in a PR (ifmain
has some changes in the kernel, and PR doesn't include it yet).This PR changes the logic from using the last commit sha to using a hash from
neonvm-kernel
directory content and the workflow file itself.
