From 95615ce5a1beffff1a5dd3597d8cb6ba83f0010e Mon Sep 17 00:00:00 2001 From: Felipe Franciosi Date: Thu, 2 Mar 2017 10:25:51 -0800 Subject: vhost-scsi: create a vhost-scsi-common abstraction In order to introduce a new vhost-user-scsi host device type, it makes sense to abstract part of vhost-scsi into a common parent class. This commit does exactly that.
