Linux内核线程没有地址空间 [英] No address space for Linux Kernel threads

问题描述

为什么Linux内核线程没有地址空间.为了执行任何任务，它应该有一个内存区域，对吗?内核线程的文本和数据在哪里?

Why the Linux kernel threads do not have an address space. For any task to execute, it should have a memory region right? Where do the text and data of kernel threads go?

推荐答案

内核线程确实具有地址空间.只是他们都共享同一个人.这并不能防止它们各自具有不同的堆栈.

Kernel threads do have an address space. It's just that they all share the same one. This does not prevent them from each having a different stack.

文本和数据在内核地址空间(所有线程共享的地址)中进行布局，具体取决于分配方式和时间以及其用途.

Text and data are laid out in the kernel address space (the one that is shared by all the threads), depending on how and when it was allocated, and what it's used for.

Linux MM 网站上有很多有关Linux这方面的文档.到那边.
