[pve-devel] [PATCH qemu-server 3/3] blockdev: delete/replace: re-use detach() helper

[Fiona Ebner]

Re-using the detach() helper has the side effect of avoiding logging
errors to syslog for automatically removed child nodes. This should be
the case for all file nodes here. None are explicitly added via
blockdev-add and thus QEMU already auto-removes them.
