Well in a way the old min/max for the limits being to strict a bug
and Jason pointed this out so I want to give him credit for that.

OTHO Fixes: feels a little bit to strong, even without a Cc: stable
tag, commits with Fixes: in there are almost guaranteed to be picked
up for the stable series and in this case that seems unnecessary to me.

If you do want to add a Fixes: tag then adding the one from patch 1/2
makes the most sense.

Regards,

Hans
