MEMBERS
name
Name of the class.
owner
The module owner.
class_attrs
Default attributes of this class.
dev_attrs
Default attributes of the devices belong to the class.
dev_groups
Default attributes of the devices that belong to the class.
dev_bin_attrs
Default binary attributes of the devices belong to the class.
dev_kobj
The kobject that represents this class and links it into the hierarchy.
dev_uevent
Called when a device is added, removed from this class, or a few other things that generate uevents to add the environment variables.
devnode
Callback to provide the devtmpfs.
class_release
Called to release this class.
dev_release
Called to release the device.
suspend
Used to put the device to sleep mode, usually to a low power state.
resume
Used to bring the device from the sleep mode.
ns_type
Callbacks so sysfs can detemine namespaces.
namespace
Namespace of the device belongs to this class.
pm
The default device power management operations of this class.
p
The private data of the driver core, no one other than the driver core can touch this.
DESCRIPTION
A class is a higher-level view of a device that abstracts out low-level implementation details. Drivers may see a SCSI disk or an ATA disk,
but, at the class level, they are all simply disks. Classes allow user space to work with devices based on what they do, rather than how
they are connected or how they work.
