$ Lock0 and $ lock1 are the identifier of the file lock. When the file is opened by a user, $ lock0 and $ lock1 are generated. When the file is not opened, it does not exist.
In fact, the most important thing is to have an identifier to indicate the current state of the file. $ lock0 and $ lock1 play this role.
