106  * ww_acquire_init - initialize a w/w acquire context
107  * @ctx: w/w acquire context to initialize
110  * Initializes an context to acquire multiple mutexes of the given w/w class.
122  * Nesting of acquire contexts for _different_ w/w classes is possible, subject
125  * An acquire context must be released with ww_acquire_fini by the same task
155  * ww_acquire_done - marks the end of the acquire phase
156  * @ctx: the acquire context
158  * Marks the end of the acquire phase, any further w/w mutex lock calls using
162  * code and clearly designated the acquire phase from actually using the locked
176  * ww_acquire_fini - releases a w/w acquire context
177  * @ctx: the acquire context to free
179  * Releases a w/w acquire context. This must be called _after_ all acquired w/w
202  * ww_mutex_lock - acquire the w/w mutex
204  * @ctx: w/w acquire context, or NULL to acquire only a single lock.
211  * for backing off by returning -EDEADLK (die case). Trying to acquire the

218  * lock and proceed with trying to acquire further w/w mutexes (e.g. when
226  * of the same w/w lock class as was used to initialize the acquire context.
233  * ww_mutex_lock_interruptible - acquire the w/w mutex, interruptible

268  * @ctx: w/w acquire context
276  * Afterwards the caller may continue to (re)acquire the other w/w mutexes it
302  * @ctx: w/w acquire context
312  * Afterwards the caller may continue to (re)acquire the other w/w mutexes it
337  * ww_mutex_trylock - tries to acquire the w/w mutex without acquire context
340  * Trylocks a mutex without acquire context, so no deadlock detection is
