23 Mutexes are represented by 'struct mutex', defined in include/linux/mutex.h
24 and implemented in kernel/locking/mutex.c. These locks use a three
37 When acquiring a mutex, there are three possible paths that can be
60      soon. The mutex spinners are queued up using MCS lock so that only
61      one spinner can compete for the mutex.

89 The mutex subsystem checks and enforces the following rules:
91     - Only one task can hold the mutex at a time.
92     - Only the owner can unlock the mutex.
95     - A mutex must only be initialized via the API (see below).
96     - A task may not exit with a mutex held.
103 In addition, the mutex debugging code also implements a number of other
118 Statically define the mutex:
121 Dynamically initialize the mutex:
122    mutex_init(mutex);
124 Acquire the mutex, uninterruptible:
125    void mutex_lock(struct mutex *lock);
126    void mutex_lock_nested(struct mutex *lock, unsigned int subclass);
127    int  mutex_trylock(struct mutex *lock);
129 Acquire the mutex, interruptible:
130    int mutex_lock_interruptible_nested(struct mutex *lock,
132    int mutex_lock_interruptible(struct mutex *lock);
134 Acquire the mutex, interruptible, if dec to 0:
135    int atomic_dec_and_mutex_lock(atomic_t *cnt, struct mutex *lock);
137 Unlock the mutex:
138    void mutex_unlock(struct mutex *lock);
140 Test if the mutex is taken:
141    int mutex_is_locked(struct mutex *lock);
