Some of the hand-held devices support hot-plugging of the cpus and when the core is hot-plugged out the /sys/devices/system/cpu/cpuX/cpufreq directory is removed too. So it won't be possible to share folders by multiple CPUs. > > -- > viresh -- 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/
