Was the intention for this to fix the xfs.mkfs hang I reported with
generic/361 + XFS?

I'm still able to reproduce that hang with this patch applied to the current
linux/master (c1ece76 (linux/master) Merge tag 'media/v4.8-5' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media)

Thanks,
