Subject: [ndctl PATCH v2 05/26] ndctl/test: Update dax-dev to handle multiple e820 ranges
Date: Sat, 27 Jul 2019 14:39:47 -0700 [thread overview]
Message-ID: <156426358717.531577.8906778081129951458.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <156426356088.531577.14828880045306313118.stgit@dwillia2-desk3.amr.corp.intel.com>
Establish a convention that the first, lowest-index, region on the e820
bus always enables in fsdax mode without need for an nd_pfn instance.
This is in preparation for a defining a collision test that requires
multiple section-mis-aligned regions defined by memmap=nn!ss.
