Hi Jens, I cloned your mq-conversions branch and ran the block, srp and nvmeof-mp test groups from the blktests project. The result of these tests on my setup is the same as with kernel v4.19: except for a few false positive lockdep complaints, all tests pass. The most recent commit that is involved in the false positive lockdep complaints I encountered is 87915adc3f0a (+ACI-workqueue: re-add lockdep dependencies for flushing+ACI). Patches are being discussed to address these false positives. Bart.
