[PATCH v1 0/2] Last minute rseq fixes for 7.0

[Mathieu Desnoyers]

Hi,

Here are two last minute rseq fixes aiming at 7.0.

The first is a clarification of a rseq registration comment to match the
rseq_size range checks.

The second ensures that the new scheduler slice extension field don't
end up exposing a rseq feature size equal to the original rseq size,
which would make life harder than it needs to be for userspace.

Thanks,

Mathieu
