Once we have a consistency model, patches and their objects will be enabled and disabled at different times. For example, when a patch is disabled, its loaded objects' funcs can remain registered with ftrace indefinitely until the unpatching operation is complete and they're no longer in use. It's less confusing if we give them different names: patches can be enabled or disabled; objects (and their funcs) can be patched or unpatched: - Enabled means that a patch is logically enabled (but not necessarily fully applied). - Patched means that an object's funcs are registered with ftrace and added to the klp_ops func stack. Also, since these states are binary, represent them with booleans instead of ints.

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.
