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.
