Subject: [PATCH bpf-next v3 2/3] selftests/bpf: do not export subtest as standalone test
Date: Sun, 30 Jan 2022 17:29:16 +0800 [thread overview]
Message-ID: <20220130092917.14544-3-hotforest@gmail.com> (raw)
In-Reply-To: <20220130092917.14544-1-hotforest@gmail.com>
Two subtests in ksyms_module.c are not qualified as static, so these
subtests are exported as standalone tests in tests.h and lead to
confusion for the output of "./test_progs -t ksyms_module".
By using the following command:
grep "^void \(serial_\)\?test_[a-zA-Z0-9_]\+(\(void\)\?)" \
tools/testing/selftests/bpf/prog_tests/*.c | \
awk -F : '{print $1}' | sort | uniq -c | awk '$1 != 1'
Find out that other tests also have the similar problem, so fix
these tests by marking subtests in these tests as static. For
xdp_adjust_frags.c, there is just one subtest, so just export
the subtest directly.
