Thanks @loader, just a minor nit in your commit message, it should be (full URL and no underscore for tags):

Differential Revision:        https://reviews.freebsd.org/D30651

Also you don't need the MFH tag.

Underscore is there because phabricator parses it, even within ` ` tags.

Also you don't need the MFH tag.

I've asked for MFH tags, because explicit > implicit, especially with regards to reasons why, or why not (in particular), a change was or wasnt merged. Part of commit commit log message standards.
