98  * ww_mutex_init - initialize the w/w mutex
100  * @ww_class: the w/w class the mutex should belong to
102  * Initialize the w/w mutex to unlocked state and associate it with the given
103  * class. Static define macro for w/w mutex is not provided and this function
104  * is the only way to properly initialize the w/w mutex.
119  * ww_acquire_init - initialize a w/w acquire context
120  * @ctx: w/w acquire context to initialize
121  * @ww_class: w/w class of the context
123  * Initializes an context to acquire multiple mutexes of the given w/w class.
125  * Context-based w/w mutex acquiring can be done in any order whatsoever within

177  * Calling this function is optional, it is just useful to document w/w mutex
192  * ww_acquire_fini - releases a w/w acquire context
195  * Releases a w/w acquire context. This must be called _after_ all acquired w/w
220  * ww_mutex_lock - acquire the w/w mutex
222  * @ctx: w/w acquire context, or NULL to acquire only a single lock.
224  * Lock the w/w mutex exclusively for this task.

284  * ww_mutex_lock_slow - slowpath acquiring of the w/w mutex
286  * @ctx: w/w acquire context
288  * Acquires a w/w mutex with the given context after a die case. This function
291  * The caller must have released all w/w mutexes already acquired with the

298  * It is forbidden to call this function with any other w/w mutexes associated
303  * ww_mutex_lock directly. This function here is simply to help w/w mutex
318  * ww_mutex_lock_slow_interruptible - slowpath acquiring of the w/w mutex, interruptible

334  * It is forbidden to call this function with any other w/w mutexes associated
340  * w/w mutex locking code readability by clearly denoting the slowpath.
358  * ww_mutex_destroy - mark a w/w mutex unusable
373  * ww_mutex_is_locked - is the w/w mutex locked
