| Subject: selftests/mm: drop unnecessary sudo usage |
| Date: Tue, 11 Mar 2025 13:18:20 +0000 |
| |
| 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. |
