The patch adds mount namespace for the container. Without the patch when we destroy the container, there still have mountinfo for the container. This is one workaroud for runC bug. If the mount namespace is disabled, when try to mount host "/" to container "/", there will cause the issue. Detail discussion as following link. "https://groups.google.com/a/opencontainers.org/forum/#!searchin/ dev/mount$20namespace%7Csort:date/dev/p10bq-kXODk/obkqBRdxCQAJ" After enable mount namespace, some small performance imapcts for specific mediator, likes USB. Will keep monitor runc community, and revert this patch once related runc patches get integrated.
