119  * ww_acquire_init - initialize a w/w acquire context
120  * @ctx: w/w acquire context to initialize
123  * Initializes an context to acquire multiple mutexes of the given w/w class.
135  * Nesting of acquire contexts for _different_ w/w classes is possible, subject
138  * An acquire context must be released with ww_acquire_fini by the same task
171  * ww_acquire_done - marks the end of the acquire phase
172  * @ctx: the acquire context
174  * Marks the end of the acquire phase, any further w/w mutex lock calls using

192  * ww_acquire_fini - releases a w/w acquire context
193  * @ctx: the acquire context to free
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.
