From 0fb5c8df609eaca3cb7c24e7f91470f8dd5984ec Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 1 Feb 2018 12:28:54 -0800 Subject: tools/testing/nvdimm: force nfit_test to depend on instrumented modules The libnvdimm unit tests will fail when they are run against the production / in-tree version of libnvdimm.ko or nfit.ko due to symbols not being mocked per nfit_test's expectation. For example, nfit_test expects acpi_evaluate_dsm() to be replaced by __wrap_acpi_evaluate_dsm() to test how acpi_nfit_ctl() responds to different stimuli. Create a test-only symbol name that nfit_test links against to cause module load failures when the wrong module is present. For example, with this change, attempts to use the wrong module will report: nfit_test: Unknown symbol libnvdimm_test (err 0) Reported-by: Dave Jiang Reported-by: Vishal Verma Signed-off-by: Dan Williams --- tools/testing/nvdimm/libnvdimm_test.c | 8 ++++++++ 1 file changed, 8 insertions(+) create mode 100644 tools/testing/nvdimm/libnvdimm_test.c (limited to 'tools/testing/nvdimm/libnvdimm_test.c') diff --git a/tools/testing/nvdimm/libnvdimm_test.c b/tools/testing/nvdimm/libnvdimm_test.c new file mode 100644 index 000000000000..00ca30b23932 --- /dev/null +++ b/tools/testing/nvdimm/libnvdimm_test.c @@ -0,0 +1,8 @@ +// SPDX-License-Identifier: GPL-2.0 +// Copyright(c) 2018 Intel Corporation.
