Linux 内核源码（kernel source）路径

• 查看内核的发行版：uname -r（--kernel-release）

  $ uname -r
  4.4.0-78-generic
  

• 内核源码所在的位置：/usr/src

  $ cd /usr/src
  $ ll
  drwxr-xr-x  8 root root 4096 May 21 04:57 ./
  drwxr-xr-x 11 root root 4096 Apr 20  2016 ../
  drwxr-xr-x 27 root root 4096 Feb 26 19:04 linux-headers-4.4.0-64/
  drwxr-xr-x  7 root root 4096 Feb 26 19:04 linux-headers-4.4.0-64-generic/
  drwxr-xr-x 27 root root 4096 May  1 01:10 linux-headers-4.4.0-75/
  drwxr-xr-x  7 root root 4096 May  1 01:10 linux-headers-4.4.0-75-generic/
  drwxr-xr-x 27 root root 4096 May 21 02:58 linux-headers-4.4.0-78/
  drwxr-xr-x  7 root root 4096 May 21 02:58 linux-headers-4.4.0-78-generic/
  lrwxrwxrwx  1 root root   32 Apr 28 09:39 vboxhost-5.1.22 -> ../share/virtualbox/src/vboxhost/
  

• 综上，这里的内核源码路径（–kernel-source-path）即为：/usr/src/linux-headers-4.4.0-78-generic/
