C++ (Cpp) lock_acquire_shared Examples

Example #1

File: active.c Project: eworm-de/bus1

void bus1_active_lockdep_acquired(struct bus1_active *active)
{
	if (active)
		lock_acquire_shared(&active->dep_map,	/* lock */
				    0,			/* subclass */
				    1,			/* try-lock */
				    NULL,		/* nest underneath */
				    _RET_IP_);		/* IP */
}

Example #2

File: lglock.c Project: 19Dan01/linux

void lg_local_lock_cpu(struct lglock *lg, int cpu)
{
	arch_spinlock_t *lock;

	preempt_disable();
	lock_acquire_shared(&lg->lock_dep_map, 0, 0, NULL, _RET_IP_);
	lock = per_cpu_ptr(lg->lock, cpu);
	arch_spin_lock(lock);
