If anyone has any objections, please let me know. ------------------ From: Michael Grzeschik [ Upstream commit 08c6b9f484a406d9d87c5b2580725d2e0597f3b9 ] When some tx or rx transfers were pending while closing the connection, the completion handler could catch one pending completion call. To ensure a normal start when mounting again, we have to reset the completion and flush any pending completions.
