Hi All, Back in commit 997b5680d139ce82c2034ba3a0d602cfd778b89b "fio: add serialize_overlap option" the feature was added to prevent write/trim race conditions within the queue. Can this feature be applied to multiple jobs? Consider: fio --ioengine=libaio --direct=1 --filename=/dev/nvme0n1 --time_based --name=test1 --rw=randwrite --runtime=5s --name=test2 --rw=randwrite --runtime=5s --serialize_overlap=1 Would we have to call in_flight_overlap() in a loop with all thread data pointers? Thanks.
