We "abused" cpusets for containerization for years, I'm not implying any 
negative connotation to it, see the 
Documentation/x86/x86_64/fake-numa-for-cpusets document that I wrote.  It 
doesn't suggest that we should be controlling thp through cpusets; if he's 
complaining about static binaries where he can't use a malloc hook then 
why not make it per-process so users don't have to configure cpusets to 
control it?
