@dachary Yes, I am aware. The first of these refers to #9496 which was reverted by #9521, so it can be dropped I think.

The second is a ceph-disk PR - which prefix would you suggest?

The third is #9238 - which prefix would you suggest?

[smithfarm]

@dachary Also, did you notice the text version of the release notes shows only the tracker issue number, and not the pr number?

build/ops seems appropriate

[ghost]

#9238 could be msg

[ghost]

did you notice the text version of the release notes shows only the tracker issue number, and not the pr number?

IIRC that was intentional to not clutter the output with references that relate to different namespaces
