The Many Names of Linux Kernels
dartttt writes "Not many people know that Kernel releases have their codenames. Most of the Linux 2.6 and 3.x kernels include a name in the Makefile of their source trees, which can be found in the git repository. They are not publicized as such but some of them are really hilarious."
This isn't a totally trivial question. I've often seen comments in forums saying that something works in kernels from the Frosty Ferret release to the Manifest Monkey release.
I think you can safely ignore anyone who refers to kernels by their silly-names. People who want to be understood uses whatever number uname -a says.
