From f295e53b60eb93ee53ed5ac610374ed293caa57b Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 17 Jun 2016 11:08:06 -0700 Subject: libnvdimm, pmem: allow nfit_test to override pmem_direct_access() Currently phys_to_pfn_t() is an exported symbol to allow nfit_test to override it and indicate that nfit_test-pmem is not device-mapped. Now, we want to enable nfit_test to operate without DMA_CMA and the pmem it provides will no longer be physically contiguous, i.e. won't be capable of supporting direct_access requests larger than a page. Make pmem_direct_access() a weak symbol so that it can be replaced by the tools/testing/nvdimm/ version, and move phys_to_pfn_t() to a static inline now that it no longer needs to be overridden.
