Hello,

My colleague Mathieu already submitted the tested patch here https://lore.kernel.org/stable/20240806122236.60183-1-mathieu.tortuyaux@gmail.com/T/#u.

Links to Flatcar patch and test run:

  * https://github.com/flatcar/scripts/pull/2194/commits/33259937abe19f612faac255706d5a509666fbc9
  * https://github.com/flatcar/scripts/actions/runs/10251425081

But this patch has been tested and submitted only for the 6.6.y branch.

It will take some time to properly test the 6.1.y, as Flatcar is going to be fully upgraded on all channels to 6.6.y, but I will come back with the patch and test results.

Thanks, Adrian.

Please provide a working backport, the change does not properly
cherry-pick.
