Subject: [PATCH 0/3] Suppress false positives triggered by workqueue lockdep annotations
Date: Thu, 25 Oct 2018 08:05:37 -0700 [thread overview]
Message-ID: <20181025150540.259281-1-bvanassche@acm.org> (raw)
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.
