That's the original plan. It were suggested by Ingo and Thomas at LKML. Borislav also send a more technical proposal about it. It actually makes sense, since some sorts of errors may affect performance (those non-fatal errors that are auto-recovered). Also, using debugfs and the same kind of logic used by perf to filter errors seems pertinent for hardware errors. As the actual patches were not written yet, the details on how those things will integrate will depend on further analysis. -- Cheers, Mauro
