Subject: [PATCH bpf-next v4 0/2] selftests: add test for kfunc call

Hi,

The patchset add a test for kfunc call to ensure s32 is sufficient for
kfunc offset. Patch #1 unexports the subtests in ksyms_module.c to fix
the confusion in test output and patch #2 adds a test in ksyms_module.c
to ensure s32 is sufficient for kfunc offset.

Change Log:
v4:
 * remove merged patch "bpf, arm64: enable kfunc call"
 * rebased on bpf-next

v3: https://lore.kernel.org/bpf/20220130092917.14544-1-hotforest@gmail.com
  * patch #2: newly-addded to unexport unnecessary subtests
  * patch #3: use kallsyms_find() instead of reimplementing it.
  * patch #3: ensure kfunc call is supported before checking
              whether s32 will be overflowed or not.

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

  selftests/bpf: do not export subtest as standalone test
