Subject: [PATCH 1/4] hostnqn: Fix the systemd-based NQN namespace to comply with the spec
Date: Thu, 19 Dec 2019 19:31:02 -0800	[thread overview]
Message-ID: <c4224eee27e76b803238048a54e6a27f8cd367b6.1576726427.git.luto@kernel.org> (raw)
In-Reply-To: <cover.1576726427.git.luto@kernel.org>

The NVME Base spec, section 7.9 explicitly states that
nqn.2014-08.org.nvmexpress:uuid: uses an RFC 4122 UUID, but we
weren't generating one.  We could change it by actually generating a
compliant UUID, but we can also just invent a new naming authority.
Use "nqn.2019-10.us.luto:sd_id128_app:"
