I don't think code sharing is realistic for that stuff, as wear levelling and all the other flash specific stuff needs to be done in the same place if you want to avoid having multiple stacked indexes, and adding wear levelling and a copying garbage collector to bcache is going to be pretty trivial at this point. But comparing notes/sharing algorithms could definitely be worthwhile. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
