Subject: [PATCH 3/4] nvme-fabrics: handle the admin-only case properly in nvmf_check_ready
Date: Mon, 11 Jun 2018 17:46:46 +0200	[thread overview]
Message-ID: <20180611154647.32558-4-hch@lst.de> (raw)
In-Reply-To: <20180611154647.32558-1-hch@lst.de>

In the ADMIN_ONLY state we don't have any I/O queues, but we should accept
all admin commands without further checks.
