From e9269b2cc403b7681980e7219cf2dc339fca8d38 Mon Sep 17 00:00:00 2001 From: Brendan Jackman Date: Tue, 11 Mar 2025 13:18:20 +0000 Subject: [PATCH] selftests/mm: drop unnecessary sudo usage This script must be run as root anyway (see all the writing to privileged files in /proc etc). Remove the unnecessary use of sudo to avoid breaking on single-user systems that don't have sudo. This also avoids confusing readers.
