2022-10-28	memory tier, sysfs: rename attribute "nodes" to "nodelist"	Huang Ying	1	-2/+2
	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.

2022-09-27	mm/demotion: expose memory tier details via sysfs	Aneesh Kumar K.V	1	-0/+25
	Add /sys/devices/virtual/memory_tiering/ where all memory tier related details can be found. All allocated memory tiers will be listed there as /sys/devices/virtual/memory_tiering/memory_tierN/ The nodes which are part of a specific memory tier can be listed via /sys/devices/virtual/memory_tiering/memory_tierN/nodes A directory hierarchy looks like :/sys/devices/virtual/memory_tiering$ tree memory_tier4/ memory_tier4/ ├── nodes ├── subsystem -> ../../../../bus/memory_tiering └── uevent :/sys/devices/virtual/memory_tiering$ cat memory_tier4/nodes 0,2 [aneesh.kumar@linux.ibm.com: drop toptier_nodes from sysfs] Link: https://lkml.kernel.org/r/20220922102201.62168-1-aneesh.kumar@linux.ibm.com Link: https://lkml.kernel.org/r/20220830081736.119281-1-aneesh.kumar@linux.ibm.com Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Cc: Alistair Popple <apopple@nvidia.com> Cc: Bharata B Rao <bharata@amd.com> Cc: Dan Williams <dan.j.williams@intel.com> Cc: Dave Hansen <dave.hansen@intel.com> Cc: Davidlohr Bueso <dave@stgolabs.net> Cc: Hesham Almatary <hesham.almatary@huawei.com> Cc: "Huang, Ying" <ying.huang@intel.com> Cc: Jagdish Gediya <jvgediya.oss@gmail.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Jonathan Cameron <Jonathan.Cameron@huawei.com> Cc: Michal Hocko <mhocko@kernel.org> Cc: Tim Chen <tim.c.chen@intel.com> Cc: Wei Xu <weixugc@google.com> Cc: Yang Shi <shy828301@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
