If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 76b12c922ec1e8f98d732bb471a2929864ab5533 Author: Sukadev Bhattiprolu <sukadev@xxxxxxxxxxxxx> Date: Thu Feb 24 22:23:52 2022 -0800 ibmvnic: initialize rc before completing wait [ Upstream commit 765559b10ce514eb1576595834f23cdc92125fee ] We should initialize ->init_done_rc before calling complete(). Otherwise the waiting thread may see ->init_done_rc as 0 before we have updated it and may assume that the CRQ was successful.
