freebsd stable - Dec 2016 - Any chance that r299900 can be merged to releng-10.3 from stable-10 ?

Hello everyone!

I'm wondering is there any chance for r299900 (git commit hash 
d99ba5cdb) to be merged to releng-10.3 ?
That error can cause our BSD fileservers to enter a panic and reboot. 
We're running that exact commit hash
on a few servers, and it's been running good for us!

We would love to have that fix and FreeBSD-EN-16:17.vm in our kernel, 
but the above patch is in 10-stable only.

What's our best solution?

Should we cherry-pick the patch into releng-10.3 and basically roll our 
own kernel?


In general we're a bit puzzled about which commits make it from 
10-stable into releng-10.3,
it seams like there are alot of bugfixes inside 10-stable which are not 
exposed to all those
who are not running/compiling their own kernels.


Any suggestions/advice is appreciated! :-)


With kind regards,

Daniel
