I'm not sure where this RC can be found. I looked at https://github.com/ceph/ ceph/releases but the v16.1.0 tag shows up as from Jan. So I'm not sure if I am looking in the correct place. I haven't tried this before so I may be looking in the wrong place. Context: I wanted to retest a go-ceph test case that is currently failing on the version of pacific available from ceph container (as of last week) [1]. If that doesn't work I wanted to try and apply a patch from a possibly related issue. But since I haven't compiled ceph before I figured I start with the RC first before trying out patches.
