Re: [PATCH v18 07/17] x86/resctrl: Prepare for new Sub-NUMA (SNC) cluster monitor files

[Reinette Chatre]

Hi Tony,

Please note in the subject (and many places in this series) the
text "Sub-NUMA (SNC)" is used. Is that intentional? Other places
it reads "Sub-NUMA Cluster (SNC)".

Just to confirm ... the reporting scope needs to be superset of
the "collecting"(?) scope. Is this something that is implicitly enforced?
