In the commitda00d2f117("bpf: Add test ops for BPF_PROG_TYPE_TRACING"), the bpf_fentry_test1 function was moved into bpf_prog_test_run_tracing(), which is the test_run function of the tracing BPF programs. Thus calling 'bpf_prog_test_run_opts(filter_fd, &topts)' will not trigger bpf_fentry_test1 function as filter_fd is a sk_filter BPF program. Fix it by replacing filter_fd with fexit_fd in the bpf_prog_test_run_opts() function.

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.
