[RFC-v3 3/4] vhost: Add vhost_scsi specific defines

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxxxxxxxx>

This patch adds the initial vhost_scsi_ioctl() callers for VHOST_SCSI_SET_ENDPOINT
and VHOST_SCSI_CLEAR_ENDPOINT respectively, and also adds struct vhost_vring_target
that is used by tcm_vhost code when locating target ports during qemu setup.
