Hi Steve, we have two APIs in Linux: - the copy_file_range syscall which just is a "do a copy by any means" - the btrfs clone ioctls which have stricter semantics that very much expect a reflink-like operation I plan to also wire up copy_file_range to try the clone_file_range method first if available to make life easier for file systems, but as there isn't any test coverage for that I don't dare to actually submit it yet. I'll send a compile tested only RFC for it when resending this series. -- 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
