From 27d676a1c2010450d00d514a8a6c1c780cb8d77f Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Thu, 20 Oct 2022 09:51:22 +0800 Subject: memory tier, sysfs: rename attribute "nodes" to "nodelist" In sysfs, we use attribute name "cpumap" or "cpus" for cpu mask and "cpulist" or "cpus_list" for cpu list. For example, in my system, $ cat /sys/devices/system/node/node0/cpumap f,ffffffff $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus 0,00100004 $ cat cat /sys/devices/system/node/node0/cpulist 0-35 $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus_list 2,20 It looks reasonable to use "nodemap" for node mask and "nodelist" for node list. So, rename the attribute to follow the naming convention.
