    ktime: Kill non-scalar ktime_t implementation for 2038 · 24e4a8c3
    John Stultz authored
    The non-scalar ktime_t implementation is basically a timespec
    which has to be changed to support dates past 2038 on 32bit
    This patch removes the non-scalar ktime_t implementation, forcing
    the scalar s64 nanosecond version on all architectures.
    This may have additional performance overhead on some 32bit
    systems when converting between ktime_t and timespec structures,
    however the majority of 32bit systems (arm and i386) were already
    using scalar ktime_t, so no performance regressions will be seen
    on those platforms.
    On affected platforms, I'm open to finding optimizations, including
    avoiding converting to timespecs where possible.
    [ tglx: We can now cleanup the ktime_t.tv64 mess, but thats a
      different issue and we can throw a coccinelle script at it ]
