[PATCH] Make spinlock/rwlock annotations more accurate by using parameters, not types
The lock annotations used on spinlocks and rwlocks currently use __{acquires,releases}(spinlock_t) and __{acquires,releases}(rwlock_t), respectively. This loses the information of which lock actually got acquired or released, and assumes a different type for the parameter of __acquires and __releases than the rest of the kernel. While the current implementations of __acquires and __releases throw away their argument, this will not always remain the case. Change this to use the lock parameter instead, to preserve this information and increase consistency in usage of __acquires and __releases.
