• 網(wǎng)絡(luò)自旋鎖；結(jié)構(gòu)鎖；自旋塊

例句

Finally, if your kernel thread shares data with a bottom half, then you can use another variant of the spinlock.

最后，如果內(nèi)核線程通過bottomhalf方式共享數(shù)據(jù)，那么可以使用自旋鎖的另一個變體。

First you create a new spinlock through a simple declaration.

首先通過一個簡單的聲明創(chuàng)建一個新的自旋鎖。

In this example, an array is created of spinlock_t with a size of LOCK_COUNT.

在這個示例中，spinlock_t創(chuàng)建一個大小為LOCK_COUNT的數(shù)組。

This version of the spinlock disables soft interrupts on the local CPU.

這種自旋鎖禁用了本地CPU上的軟中斷。

The spin_unlock_irqrestore function releases the spinlock and restores the interrupts (via the flags argument).

spin_unlock_irqrestore函數(shù)釋放自旋鎖，并且（通過flags參數(shù)）恢復(fù)中斷。

The task in the session is waiting for a spinlock to become free.

會話中的任務(wù)正在等待調(diào)節(jié)鎖變?yōu)?/c>可用。

Make sure this copying happens inside the critical section by holding a spinlock.

確保這個拷貝是在一個具有自旋鎖的臨界區(qū)中發(fā)生的。

The spin_lock_irqsave function acquires the spinlock and disables interrupts on the local processor (in the SMP case).

spin_lock_irqsave函數(shù)需要自旋鎖，并且在本地處理器（在SMP情形中）上禁用中斷。

The spinlock is needed here, because the kernel thread will be running independently and will access the global structure.

此處的確需要自旋鎖，因為內(nèi)核線程是獨立運行的，而且要訪問這個全局結(jié)構(gòu)。

Yes folks, there is a pseudo-spin lock and call to Threading. Sleep in there.

是的，各位讀者請注意，這里存在一個偽自循環(huán)鎖（pseudo-spinlock），并調(diào)用了Threading.Sleep。

I've used a combination of mutexes and spinlocks to keep things synchronized.

我使用互斥體和自旋鎖（spinlock）的組合方案來保證同步。

Now that you have a spinlock defined, there are a number of locking variants that you can use.

定義了自旋鎖之后，就可以使用大量的鎖定變量了。

There are also four ways to release a spinlock; the one you use must correspond to the function you used to take the lock

以下四種方法可以用來釋放一個自旋鎖；你必須要使用與你的鎖定函數(shù)相對應(yīng)的一個

There are actually four functions that can lock a spinlock

下面是四個可以鎖定一個自旋鎖的函數(shù)
