This patch is against 4.9. It does not apply to master due to a large rework of ion in 4.12 which removed the affected functions altogther. 4c23cbff073f3b9b ("staging: android: ion: Remove import interface")
Userspace can cause the kref to handles to increment arbitrarily high. Ensure it does not overflow.

I signed off on this? Where? When? Are you sure?

The sign off was on the 4.4.y version that I cherry-picked this from.
Ah that wasn't obvious at all. What is that git commit id? You need to give us a hint as to what is going on when you do that :)
There was a trivial conflict moving it to 4.9, but it did not modify any changed lines, so I hadn't thought that was worth noting on the patch. I apologise if leaving the signed-off-by was incorrect here.
Why did I only apply this to 4.4 and not 4.9 when the original patch was submitted? That seems odd.
thanks,
