selftests: Fix lib.mk run_tests target shell script
Within run_tests target, the whole script needs to be executed within the same shell and not as separate subshells, so the initial test_num variable set to 0 is still present when executing "test_num=`echo $$test_num+1 | bc`;". Demonstration of the issue (make run_tests): TAP version 13 (standard_in) 1: syntax error selftests: basic_test ======================================== ok 1.. selftests: basic_test [PASS] (standard_in) 1: syntax error selftests: basic_percpu_ops_test ======================================== ok 1.. selftests: basic_percpu_ops_test [PASS] (standard_in) 1: syntax error selftests: param_test ======================================== ok 1.. selftests: param_test [PASS] With fix applied: TAP version 13 selftests: basic_test ======================================== ok 1..1 selftests: basic_test [PASS] selftests: basic_percpu_ops_test ======================================== ok 1..2 selftests: basic_percpu_ops_test [PASS] selftests: param_test ======================================== ok 1..3 selftests: param_test [PASS] Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Fixes: 1f87c7c15d7 ("selftests: lib.mk: change RUN_TESTS to print messages in TAP13 format") CC: Shuah Khan <shuahkh@osg.samsung.com> CC: linux-kselftest@vger.kernel.org Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
