Proposal: Run integration tests across multiple kernel versions

It would be helpful to have visibility into how the library behaves across different kernel versions. While I haven’t spotted any bugs so far, some issues might only appear on certain LTS releases, which wouldn’t be caught by the GitHub Actions runners since they only use the kernel packaged with the runners.

One way to address this could be running the integration tests on QEMU across a range of LTS kernel versions. I realize this could make the CI pipeline heavier, so I’m opening this issue to gauge interest. If there’s interest, I’d be happy to look into implementing it.

Some features may only be available in newer kernels, so this could get a bit complex, but it might still be worthwhile. A good starting point could be to have a POC running tests on just the latest kernel version.

What do you think?
