This patch, along with the change from https://bugzilla.lustre.org/show_bug.cgi?id=18213 need to be landed on master as well. |

Hmm, I might be wrong in that this patch is only needed together with b=18213 (which allows mdc_enter_request() to be interrupted) because before that time the mdc_enter_request() thread would be blocked until it is actually removed from the list). That would still be a useful fix for master, but possibly not a blocker. Even so, I like the b1_8 code better, where the mdc_enter_request() thread removes the stack-allocated mcw struct from the list itself, rather than having the mdc_exit_request() thread do it. |

Johann, could you please comment on this one? Does the anomaly Andreas has spotted warrant being a 2.1 blocker? |

My bad. It seems that this patch was landed to master via |
