Why do we need slave_id in Kill message

[Qian AZ Zhang]

Hi,

In Kill message (scheduler.proto), I found there is a slave_id field:
  message Kill {
    required TaskID task_id = 1;
    optional SlaveID slave_id = 2;
  }

I am just wondering in which case framework needs to specify this field
when it kills a task, I think master should know the slave id of each task,
can we just use the info in master?
