With that fixed it looks good to me for .33 (but i havent tested it): Acked-by: Ingo Molnar In terms of .32 i guess it's OK too and the fix is needed - but i'd really not have done even the preceding changes - why again did we need /proc/slow_work_rq via 8fba10a and why did it have to happen right before the final kernel? If then it should have been done in debugfs - we dont need yet another /proc ABI. Also, a very small aesthetic detail: i think the title should use the 'slow-work: ' prefix, not 'SLOW_WORK: '. Thanks, Ingo
