[PATCH 3/3] rtla/osnoise: Fix error message when failing to enable trace instance

From: Daniel Bristot de Oliveira
Date: Fri Feb 18 2022 - 12:57:43 EST


When a trace instance creation fails, tools are printing:

Could not enable -> osnoiser <- tracer for tracing

Print the actual (and correct) name of the tracer it fails to enable.
