tools/testing/nvdimm: add watermarks for dax_pmem* modules Add nfit_test 'watermarks' for the dax_pmem, dax_pmem_core, and dax_pmem_compat modules. This causes the nfit_test module to fail loading in case any of these modules are also not overridden with the ldconfig wrapped modules. Without this, nfit_test would sometimes fail creation of device-dax namespaces on the nfit_test_bus with an unhelpful error log such as: dax_pmem dax5.0: could not reserve metadata dax_pmem: probe of dax5.0 failed with error -16 Which was caused due to the unwrapped version of devm_request_mem_region() being called.
