Julian Wiedmann 77868c0003 s390/qdio: add sanity checks to the fast-requeue path ... [ Upstream commit a6ec414a4d ] If the device driver were to send out a full queue's worth of SBALs, current code would end up discovering the last of those SBALs as PRIMED and erroneously skip the SIGA-w. This immediately stalls the queue. Add a check to not attempt fast-requeue in this case. While at it also make sure that the state of the previous SBAL was successfully extracted before inspecting it.
