Subject: [PATCH V2 5/7] hw/block/nvme: refactor nvme_select_ns_iocs
Date: Thu, 11 Feb 2021 01:09:35 +0900	[thread overview]
Message-ID: <20210210160937.1100-6-minwoo.im.dev@gmail.com> (raw)
In-Reply-To: <20210210160937.1100-1-minwoo.im.dev@gmail.com>

This patch has no functional changes.  This patch just refactored
nvme_select_ns_iocs() to iterate the attached namespaces of the
controlller and make it invoke __nvme_select_ns_iocs().
