    cache.h: defrag struct vsl_log
    
    There was a hole in it since we made vxid_t 64bit
    
    (gdb) ptype /o struct vsl_log
    /* offset      |    size */  type = struct vsl_log {
    /*      0      |       8 */    uint32_t *wlb;
    /*      8      |       8 */    uint32_t *wlp;
    /*     16      |       8 */    uint32_t *wle;
    /*     24      |       4 */    unsigned int wlr;
    /* XXX  4-byte hole      */
    /*     32      |       8 */    vxid_t wid;
    
                                   /* total size (bytes):   40 */
                                 }
