I already have this patch in this series:

https://lore.kernel.org/linux-fsdevel/20200507145924.GA28854@lst.de/T/#t

which is waiting to be picked up [1], and also has some chance for conflicts
due to changes next to the access_ok.

[1] except for the first two patches, which Ted plans to send for 5.7
