Hi You-Sheng, 

We are currently reviewing to see if we can apply this patch today. I'm
following up to make sure the following request is seen. 

As Stefan pointed out, the bug report does not currently have a nomination for
the Bionic main kernel. May you please confirm if we should be reviewing this
patch to apply to Bionic main?  

Thank you!
