Those apply/run on 2.6.34 with one minor change to the sixth patch: Nuke the final one-liner blob from "simplify and split bdi_start_writeback", getting rid of this part:
--- a/mm/page-writeback.c +++ b/mm/page-writeback.c @@ -705,9 +705,8 @@ void laptop_mode_timer_fn(unsigned long data) * We want to write everything out, not just down to the dirty * threshold */ - if (bdi_has_dirty_io(&q->backing_dev_info)) - bdi_start_writeback(&q->backing_dev_info, NULL, nr_pages); + bdi_start_writeback(&q->backing_dev_info, nr_pages); } /* ---- The rest applied cleanly, and I don't see any obvious need for an alternative to the deleted line above.
Cheers
