Coccinelle: A Powerful Tool for Linux Kernel Development

Coccinelle is a powerful tool for Linux kernel development, used for pattern matching and text transformation. It enables the application of complex, tree-wide patches and detects problematic coding patterns. This document details Coccinelle's installation, usage, various modes (patch, report, context, org), and advanced features such as parallelization, using a single semantic patch, controlling processed files, debugging, and .cocciconfig support. Coccinelle leverages Semantic Patch Language (SmPL) and offers multiple modes for generating patches, reports, context information, and Org-mode reports, catering to diverse needs.
