zhangyuan29 eae46b0823 sem: change sem wait to atomic operation ... Add sem_wait fast operations, use atomic to ensure atomicity of semcount operations, and do not depend on critical section. Test with robot: before modify: nxmutex_lock cost: 78 ns nxmutex_unlock cost: 82 ns after modify: nxmutex_lock cost: 28 ns nxmutex_unlock cost: 14 ns Signed-off-by: zhangyuan29 <zhangyuan29@xiaomi.com>		2024-12-17 15:40:48 +08:00
