mdadm/0082-Retire-mdassemble.patch

From 32141c1765967e37d6f1accdf124c166bc103c3b Mon Sep 17 00:00:00 2001
From: Jes Sorensen <jsorensen@fb.com>

Subject: [PATCH] Retire mdassemble
Git-commit: 32141c1765967e37d6f1accdf124c166bc103c3b
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

mdassemble doesn't handle container based arrays, no support for sysfs,
etc. It has not been actively maintained for years, so time to send it
off to retirement.
