1. 獲取倉庫
Linux kernel 的官方 GIT地址是：
穩定的倉庫： http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
Linus 大神在維護的主線： https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git
可以從這個地址拿到 kernel 的 代碼倉庫。
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git2. 查看狀態，查看分支信息：
git status
On branch master
Your branch is up-to-date with 'origin/master'.

3. 切換到分支到4.0.2：C
git checkout linux-4.0.y
Switched to branch 'linux-4.0.y' 4. 更新本地的代碼：
git feach origin
git meage origin/linux-4.0.y 5. 創建一個屬於自己的新分支：
git checkout -b linux-4.0.y-joe然後就可以開始查看代碼和進行本地修改了。
