selftests/bpf: fix a compilation error
I hit the following compilation error with gcc 4.8.5. prog_tests/flow_dissector.c: In function ‘test_flow_dissector’: prog_tests/flow_dissector.c:155:2: error: ‘for’ loop initial declarations are only allowed in C99 mode for (int i = 0; i < ARRAY_SIZE(tests); i++) { ^ prog_tests/flow_dissector.c:155:2: note: use option -std=c99 or -std=gnu99 to compile your code Let us fix the issue by avoiding this particular c99 feature. Fixes: a5cb33464e53 ("selftests/bpf: make flow dissector tests more extensible") Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
