I wouldn't want to be in a position where we merge this code in mainline, but it's just a not-very-useful toy. Then, as we turn it into a useful non-toy it all turns into an utter mess. IOW, merging this code as-is will commit us to merging more code which hasn't even been written yet. It might even commit us to solving thus-far-unknown problems which we don't know how to solve! It's a big blank cheque. So. - how useful is this code as it stands in real-world usage? - what additional work needs to be done to it? (important!) - how far are we down the design and implementation path with that new work? Are we yet at least in a position where we can say "yes, this feature can be completed and no, it won't be a horrid mess"? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
