cat: /proc/meminfo: Transport endpoint is not connected

[ruguodangshi]

Ⅰ. Issue Description

when I run "cat /proc/meminfo" in a pouch container after I run “systemctl restart pouch-lxcfs ” on the host machine，return the result “cat: /proc/meminfo: Transport endpoint is not connected”.

Ⅱ. Describe what happened

Ⅲ. Describe what you expected to happen

Should return the content of /proc/meminfo in the container normally

Ⅳ. How to reproduce it (as minimally and precisely as possible)

1.Start a pouch container
pouch run -it --enableLxcfs=true -m 512m --cpuset-cpus=5 registry.hub.docker.com/library/centos:6 bash
2.Restart lxcfs
On the host machine,run "systemctl restart pouch-lxcfs "
3.View error message
in the pouch container，run “ cat /proc/meminfo ”

Ⅴ. Anything else we need to know?

I found:

// runRemountLxcfs is the entry of remountLxcfsCommand command.
func (p *RemountLxcfsCommand) runRemountLxcfs(args []string) error {
	// TODO: get containers which enable lxcfs, and exec remount in them
	return nil
}

in remount_lxcfs.go.so,this feature has not been implemented yet?
