27d676a1 - memory tier, sysfs: rename attribute "nodes" to "nodelist"

Thu, 20 Oct 2022 01:51:22 +0000

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 2,20It looks reasonable to use "nodemap" for node mask and "nodelist" fornode list. So, rename the attribute to follow the naming convention.Link: https://lkml.kernel.org/r/20221020015122.290097-1-ying.huang@intel.comFixes: 9832fb87834e2b ("mm/demotion: expose memory tier details via sysfs")Signed-off-by: "Huang, Ying" Acked-by: Wei Xu Reviewed-by: Aneesh Kumar K.V Reviewed-by: Yang Shi Reviewed-by: Davidlohr Bueso Cc: Alistair Popple Cc: Bharata B Rao Cc: Dan Williams Cc: Dave Hansen Cc: Hesham Almatary Cc: Jagdish Gediya Cc: Johannes Weiner Cc: Jonathan Cameron Cc: Michal Hocko Cc: Tim Chen Signed-off-by: Andrew Morton List of files: /linux-6.15/Documentation/ABI/testing/sysfs-kernel-mm-memory-tiers
