The macro is prehistoric, and only exists to help those readers who don't know what memcmp() returns if memory areas differ. This is pretty well documented, so the macro looks excessive. Now that the only user of the macro depends on DEBUG_ZLIB config, GCC warns about unused macro if the library is built with W=2 against defconfig. So drop it for good.

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 reStructuredText markup notation.
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.
