12 Description:
13                 This group is the root of a policy; its name is a concatenation
14                 of an stm device name to which this policy applies and an
15                 arbitrary string. If <device> part doesn't match an existing
16                 stm device, mkdir will fail with ENODEV; if that device already
17                 has a policy assigned to it, mkdir will fail with EBUSY.

28 KernelVersion:  4.3
29 Description:
