Subject: rbd-mirror: use correct ioctx for namespace
X-Git-Tag: v17.2.8~81^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F59774%2Fhead;p=ceph.git

rbd-mirror: use correct ioctx for namespace

The PoolReplayer uses the ioctx for the default namespace
to check if other namespaces are enabled for mirroring, causing
it to incorrectly conclude that they are all enabled.

Fixes: https://tracker.ceph.com/issues/67676
