9548 | // operation to finish, and that would be the client's own fault). | |
9549 | // | |

9551 | // whatever is the state at the moment of the commit. So, if we | |
9552 | // have two clients, one issuing an unlink and another issuing a | |
9553 | // link, and if the link happens while the unlink is still on the | |
9554 | // pending state, from the link's point-of-view this is a no-op. | |

9556 | // they care about that, then the clients should make sure they | |
