From 1e06589843632afc78d2f8e9735dac3146b97988 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 2 Feb 2024 03:55:00 -0800 Subject: um: Convert strscpy() usage to 2-argument style The ARCH=um build has its own idea about strscpy()'s definition. Adjust the callers to remove the redundant sizeof() arguments ahead of treewide changes, since it needs a manual adjustment for the newly named sized_strscpy() export.
