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.
