/* * We use a raw spinlock in this exceptional case, because * we want to have the fastest, inlined, non-debug version * of a critical section, to be able to prove TSC time-warps: */ static __cpuinitdata __raw_spinlock_t sync_lock = __RAW_SPIN_LOCK_UNLOCKED; Since it's all got "__" in the front, not good to use this method all over .. If you just need a real spinlock best to use DEFINE_RAW_SPINLOCK() unless your a special situation ..
