Description Andrej K 2018-02-14 13:13:20 UTC 
In dd_main(), if skip and lseek fails, it's not checked why it happened. Thus with CONFIG_LFS, even if the offset is simply behind the large file end (EINVAL), the code still tries to seek via safe_read().

Normal coreutils are somewhat smarter about this and fail immediately...
