Subject: Re: [PATCH next v4 0/5] minmax: Relax type checks in min() and max().

I've often wondered why so many people use min_t(int, size, limit) when
they really do not want negative sizes...  Is there a performance reason?
git grep 'min_t(int,' says there are 872 instances of this.  Probably
some do want negatives but it's a quite small percent.
