1. Would you mind to push this patch to -stable?
Reason: If killing a drive was hit in the field, this should be critical enough.
2. Could you disable (at least optionally) read ahead complety on the first IO error?
Reason: In a data recovery situation (hitting EIO quite often, but not really sequentially) readahead is counter productive. E.g. trying to save an old CD with the cdparanoia software.
