Hi Neil,

The mdadm -I --no-degraded option needs to be acceptable for some time
to come, do you have a policy for when deprecated options can be scheduled for
removal?  The error code for -I shall be zero in the 'not enough' case to
restore the correct and established pre-3.1.3 behavior.

No, I don't have a policy.  Given that this was introduced fairly recently I
don't feel a need to keep it around for very long.  I'd probably be happy to
see in go in 12 months, or with mdadm-v4.0, whichever is first.

Thanks,
