Current linux kernel is not support the NVMe remap configuration, this provide a problem with access to the NVMe drive or with the new Intel Optane Memory in RAID mode.

The patch is publihed: http://lists.infradead.org/pipermail/linux-nvme/2016-October/006800.html, unfortunately is not applicable because is no a standard.
It is possible to patch the kernel anyway? Maybe via external module extension ?
