Dan Williams 3dd4fe4b4d MAINTAINERS: Move nvdimm mailing list

After seeing some users have subscription management trouble, more spam
than other Linux development lists, and considering some of the benefits
of kernel.org hosted lists, nvdimm and persistent memory development is
moving to nvdimm@lists.linux.dev.

The old list will remain up until v5.14-rc1 and shutdown thereafter.

What: /sys/bus/nd/devices/regionX/nfit/ecc_unit_size Date: Aug, 2017 KernelVersion: v4.14 (Removed v4.18) Contact: nvdimm@lists.linux.dev Description: (RO) Size of a write request to a DIMM that will not incur a read-modify-write cycle at the memory controller.

	When the nfit driver initializes it runs an ARS (Address Range
	Scrub) operation across every pmem range. Part of that process
	involves determining the ARS capabilities of a given address
	range. One of the capabilities that is reported is the 'Clear
	Uncorrectable Error Range Length Unit Size' (see: ACPI 6.2
	section 9.20.7.4 Function Index 1 - Query ARS Capabilities).
	This property indicates the boundary at which the NVDIMM may
	need to perform read-modify-write cycles to maintain ECC (Error
	Correcting Code) blocks.
