ktypes
kobjects are associated with a specific type, called a ktype . ktypes are represented by struct kobj_type and defined in <linux/kobject.h>:
struct kobj_type {
void (*release)(struct kobject *);
struct sysfs_ops *sysfs_ops;
struct attribute **default_attrs;
}; ktypes have the simple job of describing default behavior for a family of kobjects. Instead of each kobject defining its own behavior, the behavior is stored in a ktype, and kobjects of the same "type" share the same behavior.The release pointer points to the deconstructor called when a kobject's reference count reaches zero. This function is responsible for freeing any memory associated with this kobject and otherwise cleaning up.The sysfs_ops variable points to a sysfs_ops structure. This structure describes the behavior of sysfs files on read and write. It's covered in more detail in the section "Adding Files to sysfs."Finally, default_attrs points to an array of attribute structures. These structures define the default attributes associated with this kobject. Attributes represent properties related to a given object. If this kobject is exported to sysfs, the attributes are exported as files. The last entry in the array must be NULL.
