Comment 26 for bug 1874056

The backports seem to apply, compile and build fine.
The only little issue is that the backports do not come with full provenance, which is important for the Canonical kernel team.
Means that the 'Signed-off-by\|Reviewed-by\|Tested-by' lines from the upstream accepted commits need to be added to the corresponding backports, as well as a backport lines that includes the upstream commit id.
Here, especially the backport lines were all missing.
I've looked them up and added them now by hand, but would like to ask you to directly add them to the backports next time.
