FWIW, that custom interface isn't even part of the kernel. It was nice
of you to take the trouble to find out about it, and it seems that
removing the SYS time stamp will not hurt applications using the
custom interface. They will need a custom kernel in any case. However,
at the end of the day, we really don't have to support random
out-of-tree interfaces.

Thanks for doing this series.
