Sukadev Bhattiprolu 4a41c421f3 ibmvnic: serialize access to work queue on remove ... The work queue is used to queue reset requests like CHANGE-PARAM or FAILOVER resets for the worker thread. When the adapter is being removed the adapter state is set to VNIC_REMOVING and the work queue is flushed so no new work is added. However the check for adapter being removed is racy in that the adapter can go into REMOVING state just after we check and we might end up adding work just as it is being flushed (or after). The ->rwi_lock is already being used to serialize queue/dequeue work. Extend its usage ensure there is no race when scheduling/flushing work.
