++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid

++ * 2008/08/06 - 2.6.26 - (JK)
++ * - Replaced tasklet with 'netif_schedule()'.
++ * - Cleaned up and added comments for imq_nf_queue().
++ *
++ * 2009/04/12
++ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
++ * control buffer. This is needed because qdisc-layer on kernels
++ * 2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
++ * - Add better locking for IMQ device. Hopefully this will solve
++ * SMP issues. (Jussi Kivilinna)
++ * - Port to 2.6.27
++ * - Port to 2.6.28
++ * - Port to 2.6.29 + fix rmmod not working
++ *
++ * 2009/04/20 - (Jussi Kivilinna)

++ *
+ * Also, many thanks to pablo Sebastian Greco for making the initial
