    I come across this very issue when I discovered another bug,
    using un-initialized pipefs structures during early hotplug
    calls. I know about /bin/uname, but it requires a pipe, so
    wont work. Obvious alternative is /proc/sys/version, which
    is alot faster too (no fork+exec overhead).
