All the more reason to not mention the file name or really any source for the definition of the formula in the name, > 1) -e 'ratio/branch-rate/' # special event class > 2) -e 'ratio-branch-rate' # 'ratio-' prefix > 3) -e cpu/branch-rate/ # handled like aliases, ratio name would need to > be unique > ... ? I think 3 is the most extensible. Perhaps use the syntax used in other places. We have these :u suffixes etc. Perhaps have :r or :R or whatever. Given the other comments, we might want to avoid right away "ratio". If the mechanism is generalized it could be used to express "counter1 - counter2" for events which cannot be expressed with a single counter but are not really ratios. -- 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/
