Daniel Bristot de Oliveira 5e8446e382 tracing: Dump stacktrace trigger to the corresponding instance ... commit ce33c845b030c9cf768370c951bc699470b09fa7 upstream. The stacktrace event trigger is not dumping the stacktrace to the instance where it was enabled, but to the global "instance." Use the private_data, pointing to the trigger file, to figure out the corresponding trace instance, and use it in the trigger action, like snapshot_trigger does.
