Currently, compiling samples/bpf with LLVM warns about the unused but
set variable with tracex4_user.
./samples/bpf/tracex4_user.c:54:14:
warning: variable 'i' set but not used [-Wunused-but-set-variable]
int map_fd, i, j = 0;
^
1 warning generated.
This commit resolve this compiler warning by replacing the meaningless
counter.

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.
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.
