I would agree with you if the long name causes the expressions hard to read. In this particular case, it is just the single parameter to the mutex_lock() and mutex_unlock() functions. There is no confusion and overly long lines. So I think it is OK. In fact, I got the opposite advices in the past that some people prefer long descriptive names than short and cryptic names.
