Thanks Huck.  Zorro already applied v5 to the for-next branch, with the
chunk_size variable removed (which is the only code you changed in v6), and with
generic/900 renamed to its final name of generic/693.  See
https://lore.kernel.org/fstests/20220807155112.E0989C433D6@smtp.kernel.org/T/#u

So I think everything is good to go already.
