## 3.5.2 Sample Source Code

This book discusses its fair share of source code, and in many cases this source code may be found in the CodeSamples directory of this book's git tree. For example, on UNIX systems, you should be able to type:

    	find CodeSamples -name rcu_rcpls.c -print

to locate the file rcu_rcpls.c, which is called out in Section . Other types of systems have well-known ways of locating files by filename.

The source to this book may be found in the git archive at `git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/perfbook.git`, and git itself is available as part of most mainstream Linux distributions. PDFs of this book are sporadically posted at `http://kernel.org/pub/linux/kernel/people/paulmck/perfbook/perfbook.html`.
