That's fine and I'm ok for changing that to be the default now. But the shrinking could be still useful, if I read the usecase that Austin mentioned in the previous thread correctly. Say I want to prepare a minimal image but will provide a large file at the beginning because I don't know what's the resulting size going to be. In this case, something like $ mkfs.btrfs --rootdir dir/ --minimize image would make it possible. I'm not sure if somebody hasn't proposed that already, but this sounds good to me and I think it's a valid usecase. This means adding back the patch from V1 and then making it optional. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
