核心线程
内核线程
kernel───n.核心，要点；[计]内核；仁；麦粒，谷粒；精髓
thread───vi.通过；穿透过；n.线；螺纹；思路；衣服；线状物；玻璃纤维；路线；vt.穿过；穿线于；使交织
corn kernel───玉米粒
kernel function───[数]核函数
linux kernel───Linux内核
bunted kernel───包子
bobbin thread───底线，梭芯线; 梭心线
screw thread───n.螺纹
apricot kernel───[食品]杏仁；杏核油
Keventd should run to create a new kernel thread.───keventd，创建一个新的内核线程。
Each strategy requires that a kernel thread is run.───每种策略都需要运行一个内核线程。
A kernel thread is a single sequential flow of control.───内核线程是单个顺序控制流。
Softirqs were used for time-critical processing (software interrupts) in the kernel thread context.───软中断用于在内核线程上下文中处理时间要求严格的处理过程（软件中断）。
A kernel thread which is the lowest priority thread in the system - it only runs when there is no higher priority thread to run.───内核线程是系统中优先级最低的线程--仅当没有更高优先级线程运行时才能运行。
Finally, if your kernel thread shares data with a bottom half, then you can use another variant of the spinlock.───最后，如果内核线程通过bottomhalf方式共享数据，那么可以使用自旋锁的另一个变体。
The CLONE_UNTRACED flag ensures that no process will be able to trace the new kernel thread, even if the calling process is being traced.───CLONE_UNTRACED标志保证没有进程可以跟踪这个新的内核线程，即使调用进程正被跟踪。
The first one is similar to the kernel thread mentioned in the previous strategies except that it will not raise the interrupt.───第一个内核线程与在上一个策略中介绍的内核线程非常类似，区别在于它并不会触发中断。
MenTaLguY: We use userspace threads within a VM, but each VM runs in a separate kernel thread.───我们在VM中使用了用户线程，但每个VM都运行在不同的内核线程中。
User level thread is the higher level user scheduling unit supported by kernel thread, it supports concurrent execution of user programs.
The other types of code units, which you will see in later sections, are TID for kernel thread, MOD for module, and SYM for symbol (subroutine name).
