From: Arnaldo Carvalho de Melo <a...@redhat.com> Those are simple enough, and usually not produced by root, instead by whatever user is running java, rust, Node.js JIT code that end up generating those /tmp/perf-PID.map for resolution of symbols in the anonymous executable maps.
Having to use --force to resolve symbols in 'perf top' is a distraction, as recently I experienced when node.js symbols were not being resolved by 'perf top'.
