Adding Greg, cause I should probably know but I don't. 

My understanding is that Greg and Sasha scan Linus's tree periodically
and everything with a Fixes tag is pretty much guaranteed to be
selected. Whether that's a hard guarantee IDK. Would be neat if it was
so we don't have to add the CC: stable lines.

Also not sure if it's preferred to wait for the failure notification 
or you should pre-queue the backport as soon as it reaches Linus.
I vague recall someone saying to wait for the notification...
