However e.g. wait_for_completion_interruptible is also blocking, and so from this point of view it would be more logical to treat all wait_.* as a blocking point. The logic of this change actually came up for real when drivers/pci/switch/switchtec.c changed from using wait_event_interruptible to wait_for_completion_interruptible: https://lore.kernel.org/linux-pci/20190413170056.GA11293@deco.navytux.spb.ru/ https://lore.kernel.org/linux-pci/20190415145456.GA15280@deco.navytux.spb.ru/ https://lore.kernel.org/linux-pci/20190415154102.GB17661@deco.navytux.spb.ru/ For a driver that uses nonseekable_open with read/write having stream semantic and read also calling e.g. wait_for_completion_interruptible, running stream_open.cocci before this patch would produce: WARNING: _fops: .read() and .write() have stream semantic; safe to change nonseekable_open -> stream_open. while after this patch it will report: ERROR: _fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.
