pub async fn find_partition(
partition_label: &str,
device_dir: Option<&DirectoryProxy>,
) -> Result<ControllerProxy>Expand description
During the test or verify steps, finds a block device which represents an fvm partition named
[partition_label]. If [device_path] is provided, this assumes the partition is on that
device. Returns the topological path to the device, only returning once the device is
enumerated, so it can be used immediately.
