Hi, I have a setup where the process generating the perf-<pid>.map file is using pid namespaces while the perf tool is running in the global namespace. As a result, perf cannot automatically find the map file since perf only knows the global pid of the file, while the map file is named with the pid in the namespace.
The fix I have is to modify perf to search for the map file in /proc/<global pid>/root/tmp/perf-<namespace pid>.map. This works, except for one caveat, how does perf get the pid in the namespace? Is there a way for perf to extract this? I couldn't see a way. As a result, I needed to expose the pid in /proc/pid/status. Would there be a better way to achieve the same result?
