110 and rwlock_t to be implemented via RT-mutexes.
299 rwlock_t chapter
302 rwlock_t is a multiple readers and single writer lock mechanism.
308 rwlock_t and PREEMPT_RT
311 PREEMPT_RT kernels map rwlock_t to a separate rt_mutex-based
314 - All the spinlock_t changes also apply to rwlock_t.
399 spinlock_t and rwlock_t
413 Same applies to rwlock_t and the _irqsave() suffix variants.
