This header file is to be used for various macros to help make keeping the kernel ABI "stable" during an "ABI Freeze" period. They are to be used both before the freeze (to anticipate places where there will be changes), and after the freeze (to keep the abi stable for structures where there were changes due to LTS or other changes to the kernel tree.) Strongly based on rh_kabi.h from Red Hat's RHEL kernel tree. This adds support for "real" padding and the ability to replace fields with other fields. But, note that ABI changes will still be caught by libabigail at this point in time, work on that is still ongoing. When that is completed, all that will be needed is to modify the _ANDROID_KABI_RESERVE() macro in this file. No other file changes should be needed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
