Commit Message

Hou Tao Feb. 8, 2022, 6:54 a.m. UTC
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.

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
