Subject: [PATCH v1 1/5] block/vhost-user-blk-server: don't expose VHOST_USER_F_PROTOCOL_FEATURES
Date: Wed, 27 Jul 2022 16:56:49 +0100	[thread overview]
Message-ID: <20220727155653.3974426-2-alex.bennee@linaro.org> (raw)
In-Reply-To: <20220727155653.3974426-1-alex.bennee@linaro.org>

This bit is unused in actual VirtIO feature negotiation and should
only appear in the vhost-user messages between master and slave.

[AJB: experiment, this doesn't break the tests but I'm not super
confident of the range of tests]
