I can't find this by code review, and I think
maybe it's better to fix this in sysctl error path.

Indeed, we want to fix anything in the way to remove the empty sentinel,
we continue to do that in queued work on sysctl-next [0]. Although I
won't be able to diagnose this right away, could you try the out of
bounds fix by Joel [1] instead?

We want to identify what caused this and fix it within sysctl code.

Hi Luis,

Thanks of the above information. IMHO your code is good, When I cherry
pick the upstream md code for testing, the sysctl related change
leaked from my eyes. please ignore my noise. 

Great thanks for the heads up! Happy holidays.
