Why u do that? In which context do you preferred? Do you like shemaphores or spinlocks

For example in kernel 2.6 implements spinlocks are

spinlock_t my_lock = SPIN_LOCK_UNLOCKED;

Before entering a critical section, your code must obtain the requisite lock with:
void spin_lock(spinlock_t *lock);
There are actually four functions that can lock a spinlock:
void spin_lock(spinlock_t *lock);
void spin_lock_irqsave(spinlock_t *lock, unsigned long flags);
void spin_lock_irq(spinlock_t *lock);
void spin_lock_bh(spinlock_t *lock)
