Hi,

The https://www.freebsd.org/releases/14.0R/schedule/ says CURRENT/14 's KBI is froze
and new features should be avoided.

I'm working on https://reviews.freebsd.org/D39638 (sysctl(9): Enable vnet sysctl variables be loader tunable)
and I think it is new feature, but not quite sure whether the KBI changed.

So,

1. Is it a KBI change ?

2. It is a simple change ( while so far as I know currently only tested by myself on x86 and qemu riscv ), can
it catch up with 14 ?


Best regards,
Zhenlei
