Subject: Re: [PATCH next v4 0/5] minmax: Relax type checks in min() and max().
Date: Fri, 12 Jan 2024 12:13:13 +0300	[thread overview]
Message-ID: <918545c4-0870-4ea5-ab11-53eaed91aec7@moroto.mountain> (raw)
In-Reply-To: <b97faef60ad24922b530241c5d7c933c@AcuMS.aculab.com>

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.

regards,
dan carpenter
