Subject: [PATCH v4 09/12] selftests/mm: Drop unnecessary sudo usage
Date: Tue, 11 Mar 2025 13:18:20 +0000 [thread overview]
Message-ID: <20250311-mm-selftests-v4-9-dec210a658f5@google.com> (raw)
In-Reply-To: <20250311-mm-selftests-v4-0-dec210a658f5@google.com>
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.
