Well, please let me know if/when you are planning to take away
that existing ABI so I can plan accordingly. FWIW, out-of-kernel
users I am currently aware of are Juniper Networks and Zodiac
Aerospace. The latter asked me to help them upstreaming their code.

If you plan to remove the ABI, you might want to inform its current
in-kernel users. You can look those up yourself.

Thanks,
Guenter
