Subject: Re: [PATCH net-next] net: hns3: Constify static structs

From: Rikard Falkeborn <>
Date: Tue, 22 Sep 2020 00:55:17 +0200

> A number of static variables were not modified. Make them const to allow
> the compiler to put them in read-only memory. In order to do so,
> constify a couple of input pointers as well as some local pointers.
> This moves about 35Kb to read-only memory as seen by the output of the
> size command.
