            Bug ID: 611
           Summary: deadlock in example vdpa app
           Product: DPDK
           Version: 20.08
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: examples
          Assignee: dev@dpdk.org
          Reporter: xianghao3@jd.com
  Target Milestone: ---

Recently we see a deadlock in vdpa example app if SIGTERM signal is sent at
early start stage.After debuging, we suspect it's due to vhost_user.mutex is
requested twice,once by start sequence start_vdpa(), the other by SIGTERM
signal handler which calling close_vdpa().

Also checked other example apps, seems they all have same issue.
