Also the various other custom >oops-parsers which people have written themselves. Should not be a problem for ksymoops. Most entries use this regex, where [ ] is optional. #define BRACKETED_ADDRESS "\\[*<([0-9a-fA-F]{4,})>\\]* *" Printing multiple addresses (with our without [ ]) plus their symbols on the same line will stop ksymoops processing at the first symbol name, but who cares? If you can print a symbol then you already have kallsyms and you do not need ksymoops. If you do not have kallsyms then the output is just multiple addresses on one line, which ksymoops already handles. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
