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.

  kernel/workqueue: Remove lockdep annotation from __flush_work()
  kernel/workqueue: Surround work execution with shared lock annotations
  kernel/workqueue: Suppress a false positive lockdep complaint
