Subject: [PATCH bpf-next v5] selftests/bpf: do not export subtest as standalone test
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.
Signed-off-by: Hou Tao <houtao1@...wei.com>

v5:
* keep the only subtest in xdp_adjust_frags.c to follow
the naming convention for test
v4: https://lore.kernel.org/bpf/20220206043107.18549-1-houtao1@huawei.com
* rebased on bpf-next
v3: https://lore.kernel.org/bpf/20220130092917.14544-1-hotforest@gmail.com
* add a new patch to unexport unnecessary subtests
v2: https://lore.kernel.org/bpf/20220127071532.384888-1-houtao1@huawei.com
* add a test to check whether imm will be overflowed for kfunc call
v1: https://lore.kernel.org/bpf/20220119144942.305568-1-houtao1@huawei.com
