That the direct io function needed a valid bdev just for the prefetch
but nothing else was one of the reasons we had to keep the latest_bdev
in btrfs, so good riddance.
You may want to add the reference to the patch that added the prefetch,
65dd2aa90aa1 ("dio: optimize cache misses in the submission path") and
also remove #include <linux/prefetch.h> as there are no more uses of
prefetch in the file.
With that
