The crash tool requires the dwarf data to work. The dwarf data for an entire kernel (including all the modules) is on the order of hundreds of megabytes. The symbol & marker list would be one thousandth the size. You can see the deployment attractiveness of the latter. > I guess you must already need to extract the symbols for your kprobes. > Do you use kallsyms for this? Nope. /proc/kallsyms is a another run-time-only source of data, and so is not applicable for off-line (ahead-of-time) mapping. > I would rather prefer not to implement superfluous built-time data > extraction in the kernel build system just to make userspace > simpler. [...] It is not superfluous, as it would solve a real distribution problem. - FChE - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
