selftests/bpf: Add test result messages for test_task_storage_map_stress_lookup
Add test result message when test_task_storage_map_stress_lookup() succeeds or is skipped. The test case can be skipped due to the choose of preemption model in kernel config, so export skips in test_maps.c and increase it when needed. The following is the output of test_maps when the test case succeeds or is skipped: test_task_storage_map_stress_lookup:PASS test_maps: OK, 0 SKIPPED test_task_storage_map_stress_lookup SKIP (no CONFIG_PREEMPT) test_maps: OK, 1 SKIPPED Fixes: 73b97bc78b32 ("selftests/bpf: Test concurrent updates on bpf_task_storage_busy") Signed-off-by: Hou Tao <houtao1@huawei.com> Link: https://lore.kernel.org/r/20220919035714.2195144-1-houtao@huaweicloud.com Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>
