1 The device-mapper uevent code adds the capability to device-mapper to create
  2 and send kobject uevents (uevents).  Previously device-mapper events were only
  3 available through the ioctl interface.  The advantage of the uevents interface
  4 is the event contains environment attributes providing increased context for
  5 the event avoiding the need to query the state of the device-mapper device after
  6 the event is received.
  7 创建的device-mapper UEVENT代码添加能力的device-mapper
  ，并发送kobject的uevents（uevents）。此前的device-mapper事件
  可通过ioctl接口。的uevents接口的优点
  事件包含提供更多的上下文环境属性
  事件后避免需要查询的device-mapper设备的状态
  接收到事件。


  8 There are two functions currently for device-mapper events.  The first function
  9 listed creates the event and the second function sends the event(s).
 10 目前的device-mapper事件有两个函数。第一个函数
  上市的创建事件，而第二个函数发送事件（次）。
 11 void dm_path_uevent(enum dm_uevent_type event_type, struct dm_target *ti,
 12                     const char *path, unsigned nr_valid_paths)
 13 无效dm_path_uevent（枚举，结构dm_target* TI dm_uevent_type EVENT_TYPE，
    为const char*路径，无符号nr_valid_paths），
 14 void dm_send_uevents(struct list_head *events, struct kobject *kobj)
 15 的无效dm_send_uevents（结构的list_head*事件，结构的kobject* kobj的）
 16 
 17 The variables added to the uevent environment are:
 18 添加的uevent环境的变量是：
 19 Variable Name: DM_TARGET
