[$] LCA: The Trinity fuzz tester

The Linux kernel developers have long been aware of the need for better testing of the kernel. That testing can take many forms, including testing for performance regressions and testing for build and boot regressions. As the term suggests, regression testing is concerned with detecting cases where a new kernel version causes problems in code or features that already existed in previous versions of the kernel. Of course, each new kernel release also adds new features. The Trinity fuzz tester is a tool that aims to improve testing of one class of new (and existing) features: the system call interfaces that the kernel presents to user space.
