Subject: [PATCH v2 6/8] ext4: update the descriptions of data_err=abort and data_err=ignore

From: Baokun Li <libaokun1@...wei.com>

We now print error messages in ext4_end_bio() when page writeback
encounters an error. If data_err=abort is set, the journal will also
be aborted in a kworker. This means that we now check all Buffer I/O
in all modes and decide whether to abort the journal based on the
data_err option. Therefore, we remove the ordered mode restriction
in the descriptions of data_err=abort and data_err=ignore.
