linux - 了解 linux 内核和补丁发布

Question

我想更好地了解 linux 内核/补丁发布的工作原理。

例如，如果我今天(2013 年 12 月 12 日)打开 www.kernel.org，主要下载(黄色按钮)会将我带到最新稳定版“linux-3.12.5.tar.xx”。这很清楚。

但是如果我进入“https://www.kernel.org/pub/linux/kernel/v3.x/”，我可以找到(在许多文件中):

(1) linux-3.12.tar.gz

(2) 补丁-3.12.5.gz

(3) 补丁-3.12.gz

所以第一个问题:是"linux-3.12.5"= (1)linux-3.12 "+"(2)patch-3.12.5?

如果是这样，“patch-3.12”(3) 的用途是什么？ "linux-3.12"= linux-3.11 "+"(3)patch-3.12 像上面那样吗？

谢谢!

根据 https://github.com/torvalds/linux/blob/master/README (从第 95 行开始):

Unlike patches for the 3.x kernels, patches for the 3.x.y kernels (also known as the -stable kernels) are not incremental but instead apply directly to the base 3.x kernel. For example, if your base kernel is 3.0 and you want to apply the 3.0.3 patch, you must not first apply the 3.0.1 and 3.0.2 patches. Similarly, if you are running kernel version 3.0.2 and want to jump to 3.0.3, you must first reverse the 3.0.2 patch (that is, patch -R) before applying the 3.0.3 patch. You can read more on this in Documentation/applying-patches.txt
