Hi Tejun, In my tests with kernel v4.19 I noticed that several new false positive reports were generated by the workqueue lockdep annotations. This patch series addresses one of these false positives. Another false positive will be addressed by a patch for the NVMe target driver. Please consider these patches for the upstream kernel.
Thanks, Bart.
