    timex: use __kernel_timex internally · ead25417
    Deepa Dinamani authored
    struct timex is not y2038 safe.
    Replace all uses of timex with y2038 safe __kernel_timex.
    
    Note that struct __kernel_timex is an ABI interface definition.
    We could define a new structure based on __kernel_timex that
    is only available internally instead. Right now, there isn't
    a strong motivation for this as the structure is isolated to
    a few defined struct timex interfaces and such a structure would
    be exactly the same as struct timex.
