Where is this limit introduced ? I do not see it anywhere in your patches. Did I
miss something ?

Hi Damien,

Please take another look at patch 01/18 of this series. I think that you
have seen that patch before since a Reviewed-by tag was posted by you on
August 17. See also https://lore.kernel.org/linux-block/6d823671-db2b-2280-0c93-87d03a2f471e@xxxxxxxxxx/.

Thanks,

Bart.
