OK, will make it atomic in next version, thanks for the advice.

Perhaps I can add two scsi helper functions in scsi_lib.c like:

void sdev_disable_disk_events(struct scsi_device *sdev)
{
	atomic_inc(&sdev->disk_events_disable_depth);
}

void sdev_enable_disk_events(struct scsi_device *sdev)
{
	if (WARN_ON_ONCE(atomic_read(&sdev->disk_events_disable_depth) <= 0))
		return;
	atomic_dec(&sdev->disk_events_disable_depth);
}

And call them in ATA layer. Do you like this?

Sounds good to me.  James, how does the series look to you?

Indeed.  Want James' Acked-by for patch #1.

I think it's ready. It can go into libata-dev.git #upstream, and be reverted prior to Linus push if James NAKs.
