Dear Chunfeng,
Since this issue has been reported by Canonical as a ticket
on launchpad (sorry, it has been reported as a private ticket...),
could you please to check if add "Cc: stable@vger.kernel.org" and
"Fixes:" tags are valid?
If it is possible, please help to list dependent patches to backport
to stable tree also. Is it possible to include this patch in recent LTS
tree?
Thanks
Macpaul Lin
