I thought we had landed a fix for this (or a similar) problem, but I can't find it. Thanks for sending the patch. |

Status update: Vitaly and Johann Lombardi discuss this patch (should we use force_Sync flag for the commit or not). |

The patch in http://review.whamcloud.com/2077 (which just landed on b1_8) unfortunately had a defect in it. I've pushed a fix in http://review.whamcloud.com/4729. |
