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.
Updates since v2:
- Update comment above struct rseq in the uapi header.
Thanks,
Mathieu
