While userspace doesn't fill the dimm labels, add there the dimm location, as described by the used memory model. This could eventually match what is described at the dmidecode, making easier for people to identify the memory. For example, on an Intel motherboard where the DMI table is reliable, the first memory stick is described as: Memory Device Array Handle: 0x0029 Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 2048 MB Form Factor: DIMM Set: 1 Locator: A1_DIMM0 Bank Locator: A1_Node0_Channel0_Dimm0 Type: <OUT OF SPEC> Type Detail: Synchronous Speed: 800 MHz Manufacturer: A1_Manufacturer0 Serial Number: A1_SerNum0 Asset Tag: A1_AssetTagNum0 Part Number: A1_PartNum0 The memory named as "A1_DIMM0" is physically located at the first memory controller (node 0), at channel 0, dimm slot 0. After this patch, the memory label will be filled with: /sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0 And (after the new EDAC API patches) as: /sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0 So, even if the memory label is not initialized on userspace, an useful information with the error location is filled there, expecially since several systems/motherboards are provided with enough info to map from channel/slot (or branch/channel/slot) into the DIMM label. So, letting the EDAC core fill it by default is a good thing. It should noticed that, as the label filling happens at the edac_mc_alloc(), drivers can override it to better describe the memories (and some actually do it).
