Does a "goto" statement jump to the code position finally which is specified by the label?

Do you find information from a commit like "docs: Remove space-before-label guidance from CodingStyle" (from 2016-09-21) interesting? ;-) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/Documentation/CodingStyle?id=79c70c304b0b443429b2a0019518532c5162817a
