Feedback form is now closed.
The Linux kernel has a number of unwritten idioms and design patterns that are used for optimal development and code efficiency. This talk seeks to illustrate these coding patterns, and help developers implement Linux kernel code in the "upstream way".

Tim will describe some of the kernel idioms for error handling, use of gotos, structures with embedded data and links, use of function pointers, when to use ifdefs, inlines and macros, structure initialization, and more. Each pattern will be explained, with examples, and the rationale for each pattern will be provided.

The purpose is to allow a developer to write code that is not only efficient, making best use of kernel interfaces, but also to make the code easier to maintain and easier to be contribute upstream, with less correction required for acceptance into mainline.
