Andrew, Mel, This struct page stuffing is taking a lot of time to work out and _might_ be fraught with peril when memmap peekers are considered. What do you think about just storing the zbud page metadata inline in the memory page in the first zbud page chunk? Mel, this kinda hurts you plans for making NCHUNKS = 2, since there would only be one chunk available for storage and would make zbud useless. Just a way to sidestep this whole issue. What do you think? Seth -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
