Sure but the most common and important case is good then. in fs/ubifs/file.c we use a fixed buffer size of UBIFS_MAX_DATA_NODE_SZ to deal with data nodes. So, dumping is safe.
If we don't know the buffer size for minor cases, not a big deal. Still better than giving up the feature completely.
Thanks, //richard
