[RFC PATCH 07/11] block: Make partitions inherit namespace from whole disk device

From: Seth Forshee
Date: Wed May 14 2014 - 17:37:00 EST


When adding block devices for paritions the devices default to
ownership by init_user_ns. Instead assign them to the same
namespace as the device for the whole disk.
