    Subject[PATCH 3/14] drivers/vhost/vhost.c: delete double assignment
    Date
    From: Julia Lawall <julia@diku.dk>

    Delete successive assignments to the same location.

    A simplified version of the semantic match that finds this problem is as
    follows: (http://coccinelle.lip6.fr/)

    // <smpl>
    @@
    expression i;
    @@

    *i = ...;
    i = ...;
    // </smpl>
