That will tell you exactly what kernel packages you installed. It sounds like you installed the kernel source rather than the kernel to me. 180MB is too big for a kernel but about right for the kernel source; kernels are usually in the neighborhood of 20 to 30MB. The above output will tell for sure.
rpm -qa | grep kernel
so what is the real difference between the kernel source (issued as part of a security update) and the kernel ?
I am sure you are correct but I would like to understand the difference.
