[PATCH v2 0/7] vhost-scsi: Fix crashes and management op hangs
The following patches were made over Linus tree. The patches fix 3
issues:
1. If a user performs LIO LUN unmapping before the endpoint has been
cleared then we can end up trying to free a bogus tmf struct if the
TMF is still exucuting when we do the unmap.
2. If vhost_scsi_setup_vq_cmds fails we can leave the tpg->vhost_scsi
pointer set and we can end up trying to access a freed struct.
3.
