Author: bwidawsk Date: Fri Feb 22 19:54:21 2019 New Revision: 344474 URL: https://svnweb.freebsd.org/changeset/base/344474
Log: nvdimm: split spa dev into a separate entity Separate code for exposing a device backed by a system physical address range away from the NVDIMM spa code. This will allow a future patch to add support for NVDIMM namespaces while using the same device code.
