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 <dave.jiang@intel.com> Reported-by: Vishal Verma <vishal.l.verma@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
