    xfrm: Flushing empty SAD generates false events · 19f4c713
    jamal authored
    To see the effect make sure you have an empty SAD.
    -On window1 "ip xfrm mon"
    -on window2 issue "ip xfrm state flush"
    You get prompt back in window1
    and you see the flush event on window2.
    With this fix, you still get prompt on window1 but no
    event on window2.
    
    I was tempted to return -ESRCH on window1 (which would
    show "RTNETLINK answers: No such process") but didnt want
    to change current behavior.
    
    cheers,
