+ update "BFQ-v6-I-O-sched" (for-3.4) -> http://algo.ing.unimo.it/people/paolo/disk_sched/

only thing that I have changed, for compiling ... ->

-------------------
block/bfq-iosched.c
-------------------
        /* handle changed prio notifications; cgroup change is handled separately */
-       if (unlikely(bic->icq.changed))
-               if (test_and_clear_bit(ICQ_IOPRIO_CHANGED, &bic->icq.changed))
-                       bfq_changed_ioprio(bic->icq.ioc, bic);
+       if (unlikely(icq_get_changed(&bic->icq) & ICQ_IOPRIO_CHANGED))
+               bfq_changed_ioprio(bic->icq.ioc, bic);
Allow to see build errors if there are any. none for now.
