Do you have userspace making use of DRM_CRTC_SEQUENCE_NEXT_ON_MISS? If not, drop it.

I added this so that the new ioctl would be compatible with the old ioctl; do you think that's unnecessary?

I do. I don't know if there's ever been any real-world usage of DRM_VBLANK_NEXTONMISS. Let's not repeat my mistake in the new interface.
