kernel-devel is necessary to build modules such as devices
On CentOS(rpm-based OS), install Linux Kernel-devel with consistency with kernel
By the way, kernel-devel seems to contain the minimum source necessary for building modules
[vagrant@localhost ~]$ rpm -qa | grep kernel
kernel-devel-2.6.32-754.2.1.el6.x86_64
kernel-2.6.32-754.3.5.el6.x86_64

kernel-devel, kernel-headers ともに入ってますね。
kernel-headers
A C language header file related to the kernel is packaged.
It is necessary for rebuilding the kernel and compiling system related programs.

Summary : Header files for the Linux kernel for use by glibc
Description :
Kernel-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs. The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
glibc package.
ん？ Linux kernelのことか？
