[CRIU] external mountpoint issue for docker

[Bing X]

ok, I make $odir as a new mountpoint with the command:

mount -t tmpfs none "./$odir"

then run privot_root command:

pivot_root "/var/lib/docker/containers/a4aec40cc802b258990c538852387b
14ec7f7404ca397c66f2ee6ff9862f4a16/root/" "./$odir

still get the same error: Invalid argument.

am I wrong on making $odir a new mountpoint? if so, what's the correct
command?

thanks,
Bing
