10                                   const struct attribute_group ** groups);

14           virtual subsystem
15
16       groups
17           default attributes for the root device

DESCRIPTION

20       All 'virtual' subsystems have a /sys/devices/system/<name> root device
21       with the name of the subystem. The root device can carry subsystem-wide
22       attributes. All registered devices are below this single root device.
23       There's no restriction on device naming. This is for kernel software
24       constructs which need sysfs interface.
