I made a number of changelog changes: - Rewrote it as From: Andrea (correct?) - Replaced your acked-by with signed-off-by, as you were on the delivery path - Hunted down Arthur's email address and added his reported-by and tested-by. - Added cc:stable, as it's a bit late for 2.6.38. The intention being that we put this into 2.6.38.1 after it has cooked in 2.6.39-rcX for a while. OK? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
