Subject: [PATCH 0/2] target: Introduce dummy devices
Date: Thu, 18 Mar 2021 12:42:23 +0300	[thread overview]
Message-ID: <20210318094224.17524-1-k.shelekhin@yadro.com> (raw)

This patch series (inspired by SCST) adds support for the dummy devices
via the new DUMMY flag of rd_mcp. The rationale behind the change is to
give a user the ability to create conifgurable devices for LUN 0 with
custom WWN values (like vendor, product or revision) as some tools like
QConvergeGUI use LUN 0 to identify the whole storage.

The advantage over simply creating a NULLIO rd_mcp device is that the
DUMMY device will not be seen as a block device, hence less confusion
for the system administrator.

  target: Add the DUMMY flag to rd_mcp
