Looks fine to me - and I think it can probably go through the arm64 tree since you'd be the only one really testing it anyway.
I assume you checked that btrfs is the only one that uses fault_in_writeable() in this way? Everybody else updates to the right byte boundary and retries (or returns immediately)?
