Will this change the current Ctrl-C behavior in other places in any way? Right now Ctrl-C behavior is pretty sensible: it essentially means instant abort of whatever was done, i.e. stepping back a level in 'perf top', exit the app if it's done at the highest level. I hope that's preserved! :-) Thanks, Ingo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
