To start with the last point: No, I do not expect that there is any
impact on production.
So we could also try to ignore just these tests.
#29968 is a nobrainer to backport.
#29862 required extra fixes. (quite some might be overstated)
Since a pactch might be acceptable, I'll put some efforts in it.
Can I create ONE PR that holds several cherry-picks, and some custom
commits?
Sure. I think it’s fine. Presumably they are not touching lots of different components in Ceph.
Otherwise I'll just use #29862 as basis to create a new PR.
