Did you by change pull plain net-2.6 into that tree?  Because one
commit which is in net-2.6 but not in net-next-2.6 catches my eye:

commit c486da34390846b430896a407b47f0cea3a4189c

    sysctl: ipv6: use correct net in ipv6_sysctl_rtcache_flush
    
    Before this patch issuing these commands:
    
      fd = open("/proc/sys/net/ipv6/route/flush")
      unshare(CLONE_NEWNET)
      write(fd, "stuff")
    
    would flush the newly created net, not the original one.
    
    The equivalent ipv4 code is correct (stores the net inside ->extra1).
