Description

sudo GLOG_v=1 ./bin/mesos-tests.sh --gtest_filter="LinuxFilesystemIsolatorTest.ROOT_VolumeFromHostSandboxMountPoint" --verbose

failed in Ubuntu 14.04

Just a problem when investing MESOS-3349 PersistentVolumeTest.AccessPersistentVolume fails when run as root.

In LinuxFilesystemIsolatorProcess::cleanup, when we read mount table and umount. The order should use reverse order. Suppose our mount order is

mount /tmp/a /tmp/b
mount /tmp/c /tmp/b/c

Currently we umount logic in cleanup is

umount /tmp/b
umount /tmp/b/c <- Wrong

This is the reason why ROOT_VolumeFromHostSandboxMountPoint failed.
