Subject: [PATCH v3] vhost_vdpa: fix the problem in vhost_vdpa_set_config_call
Date: Tue, 12 Jan 2021 13:36:29 +0800 [thread overview]
Message-ID: <20210112053629.9853-1-lulu@redhat.com> (raw)
In vhost_vdpa_set_config_call, the cb.private should be vhost_vdpa.
this cb.private will finally use in vhost_vdpa_config_cb as
vhost_vdpa. Fix this issue.
Fixes: 776f395004d82 ("vhost_vdpa: Support config interrupt in vdpa")
