214 raw_spinlock_t is a strict spinning lock implementation in all kernels,
215 including PREEMPT_RT kernels. Use raw_spinlock_t only in real critical
218 hardware state. raw_spinlock_t can sometimes also be used when the

497 spinlocks are preserved on PREEMPT_RT kernels, so that the raw_spinlock_t
