Wang Weiyang 35fe1c2384 device_cgroup: Roll back to original exceptions after copy failure ... commit e68bfbd3b3 upstream. When add the 'a *:* rwm' entry to devcgroup A's whitelist, at first A's exceptions will be cleaned and A's behavior is changed to DEVCG_DEFAULT_ALLOW. Then parent's exceptions will be copyed to A's whitelist. If copy failure occurs, just return leaving A to grant permissions to all devices. And A may grant more permissions than parent. Backup A's whitelist and recover original exceptions after copy failure.
