You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: unpause.go
    path of file: ./repos/docker-ce/components/engine/daemon
    
    the code of the file until where you have to start completion: package daemon // import "github.com/docker/docker/daemon"

import (
	"context"
	"fmt"

	"github.com/docker/docker/container"
	"github.com/sirupsen/logrus"
)

// ContainerUnpause unpauses a container
func (daemon *Daemon) ContainerUnpause(name string) error {
	ctr, err := daemon.GetContainer(name)
	if err != nil {
		return err
	}
	return daemon.containerUnpause(ctr)
}

// containerUnpause resumes the container execution after the container
    
func (daemon *Daemon) containerUnpause(ctr *container.Container) error {
	ctr.Lock()
	defer ctr.Unlock()

	// We cannot unpause the container which is not paused
	if !ctr.Paused {
		return fmt.Errorf("Container %s is not paused", ctr.ID)
	}

	if err := daemon.containerd.Resume(context.Background(), ctr.ID); err != nil {
		return fmt.Errorf("Cannot unpause container %s: %s", ctr.ID, err)
	}

	ctr.Paused = false
	daemon.setStateCounter(ctr)
	daemon.updateHealthMonitor(ctr)
	daemon.LogContainerEvent(ctr, "unpause")

	if err := ctr.CheckpointTo(daemon.containersReplica); err != nil {
		logrus.WithError(err).Warn("could not save container to disk")
	}

	return nil
}
