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.

Description: Directory with details of a specific memory tier
|
|
|
|
This is the directory containing information about a particular
|
|
memory tier, memtierN, where N is derived based on abstract distance.
|
|
|
|
A smaller value of N implies a higher (faster) memory tier in the
|
|
hierarchy.
|
|
|
|
nodelist: NUMA nodes that are part of this memory tier.
