Recently, I encountered a interesting phenomenon that CentOS 6.3
running as normal even if I (my colleague, actually) installed a
kernel that build for CentOS 7.x (e.g. kernel-3.10.0-327.el7.x86_64.rpm).

I found kernel is mismatch accidentally when I using "uname -r" to
check kernel version. So my question is what the harmness we will
get if I install a el7 rpm into a el6 system?
