Linux source code tree

Linux source code tree-Linux general technology-Linux programming and kernel information. The following is a detailed description. Linux is used to support the source code of various architectures. It contains about 4500 C language programs and is stored in around 270 subdirectories. It contains about 2 million lines of code in total, which occupies about MB of disk space.

Source code is in the directory:/usr/src/linux (in most linux releases)
