I suspect this has occured because this rebase was not done from the correct tag.

Now I am not 100% convinced we have lost the actual change, bit it would be good confirm that please. If this is present just that the changelog is missformed then we can move this back to Confirmed and accept it, assuming we get the changelog fragment restored for the next upload.

@Andy That change was not lost, it is now known as

b6c15098fa292 blk-wbt: fix performance regression in wbt scale_up/scale_down

and is part of the parent kernel Ubuntu-gcp-5.0.0-1024.24

I will change the status back to confirmed as you suggested, and I have a note ForNextCycle to fix the changelog. I'm not exactly sure how to do that, but I can figure it out then.

[Khaled El Mously (kmously)]

Changed the 'promoted-to-proposed' status back to confirmed, as per previous comment.
