I.e. are the any known issues that make things work than current mainline if we only put in patches 1 to 6? We're getting close to another merge window, and we're still busy trying to figure out all the details of the bandwith estimation. I think we'd have a much more robust tree if we'd first only merge the infrastructure (IO-less balance_dirty_pages()) and then work on the algorithms separately. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
