If a pstore record has its ecc_notice_size field set to >0, it means the record's buffer has that many additional bytes appended to the end that carry backend specific metadata, typically used for error correction. Given that this is backend specific, and that user space cannot really make sense of this metadata anyway, let's not expose it via the pstore filesystem.
