Perhaps that's just my silly imagination but 'diff' doesn't look good for the name of a variable to hold a result of a three-way-comparison (-1, 0, 1) which is what ->cmp_key_with_cur() does. It implies to contain an actual difference between the two integer variables but that's not true anymore after recent refactoring. Declaring it as int64_t is also misleading now. Plain integer type is more than enough. Found by Linux Verification Center (linuxtesting.org). Signed-off-by: Fedor Pchelkin <pchelkin@ispras.ru> Reviewed-by: Darrick J.

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.
