From d4df9aa412dae212d7a67ae45373f479bd1b8c09 Mon Sep 17 00:00:00 2001
From: ngie <ngie@ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f>
Date: Sun, 13 Mar 2016 01:14:07 +0000
Subject: [PATCH] MFC r293438:

- Add a geom_raid3 specific cleanup function and trap on that function at
  exit so things are cleaned up properly
- Use attach_md for attaching md(4) devices
- Don't hardcode /tmp for temporary files, which violates the kyua sandbox
