The pred_funcs_##type arrays consist of five functions that are assigned based on the ops. The array must be in the same order of the ops each function represents. The PRED_FUNC_START macro denotes the op enum that starts the op that maps to the pred_funcs_##type arrays. This is all very subtle and prone to bugs if the code is changed. Add comments describing how PRED_FUNC_START and pred_funcs_##type array is used, and also a PRED_FUNC_MAX that is the maximum number of functions in the arrays. Clean up select_comparison_fn() that assigns the predicates to the pred_funcs_##type array function as well as add protection in case an op is passed in that does not map correctly to the array.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
