linux-toradex.git/drivers/nvdimm/claim.c, branch v4.4.7 Linux kernel for Apalis and Colibri modules libnvdimm, pfn: 'struct page' provider infrastructure 2015-08-29T03:39:36+00:00 Dan Williams dan.j.williams@intel.com 2015-07-30T21:57:47+00:00 e1455744b27c9e6115c3508a7b2902157c2c4347 Implement the base infrastructure for libnvdimm PFN devices. Similar to BTT devices they take a namespace as a backing device and layer functionality on top. In this case the functionality is reserving space for an array of 'struct page' entries to be handed out through pfn_to_page(). For now this is just the basic libnvdimm-device-model for configuring the base PFN device. As the namespace claiming mechanism for PFN devices is mostly identical to BTT devices drivers/nvdimm/claim.c is created to house the common bits.
