Also, even though pgcl scales "perfectly" wrt. highmem (nm the code being a train wreck), the raw capacity increase is needed. There are enough other reasons to go through with ABI-preserving page clustering that they're not really in competition with each other. Looks good to me. I'll spin it up tonight. -- wli -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
