That seems like a bug waitig to happen.
This is intentional to a certain degree: we don't have a timeval64 because any conversion to a new interface should prefer timespec64 or 64-bit nanoseconds, and we try to remove timeval (along with timespec) from everywhere in the kernel because basically all uses are problematic for y2038. Note that after patch 3, event->time is no longer a 'timeval' either, so even if we had a conversion function, we could no longer use it here.
