Subject: [PATCH 14/14] hw/nvme: move nvme emulation out of hw/block
Date: Mon, 19 Apr 2021 21:28:01 +0200	[thread overview]
Message-ID: <20210419192801.62255-15-its@irrelevant.dk> (raw)
In-Reply-To: <20210419192801.62255-1-its@irrelevant.dk>

From: Klaus Jensen <k.jensen@samsung.com>

With the introduction of the nvme-subsystem device we are really
cluttering up the hw/block directory.

As suggested by Philippe previously, move the nvme emulation to hw/nvme.

Suggested-by: Philippe Mathieu-Daudé <philmd@redhat.com>
