From: Jan Kara <jack@xxxxxxx> [ Upstream commit c0e71d602053e4e7637e4bc7d0bc9603ea77a33f ] When a kernel is configured without CONFIG_DEV_DAX_PMEM_COMPAT, the compilation of tools/testing/nvdimm fails with: Building modules, stage 2. MODPOST 11 modules ERROR: "dax_pmem_compat_test" [tools/testing/nvdimm/test/nfit_test.ko] undefined! Fix the problem by calling dax_pmem_compat_test() only if the kernel has the required functionality.
