From: Heinz Mauelshagen <heinzm@xxxxxxxxxx> Lidong, thanks for sending your patch proposal. The error endio log path seems wrong, because the patch fails the io in case "keep_log" is set and the log is _not_ errored. It should be failed (as the comment explains), when "keep_log" is set and the log has failed. See your patch rebased to 4.0.0-rc7 and mine as 1+2 of this series.
