Apologies. I typed too fast.

Is this option already available somewhere in code, or would that be a =
proposed one?

I get tens of thousands of those warnings a day per server. Thankfully, =
they are =E2=80=9Crolled-up=E2=80=9D with counts, but it still makes a =
few hundred to low thousands of lines in the log and email reports. It =
would be great to suppress it altogether till 2019 when FreeBSD 12 comes =
out.

Many thanks,
