Subject: [PATCH] mm/oom_kill: Remove unnecessary integer promotion in format string
Date: Sun, 28 Dec 2025 15:44:55 +0000	[thread overview]
Message-ID: <20251228154456.2386-1-kdipendra88@gmail.com> (raw)

The 'h' length modifier in '%hd' is unnecessary as short integers are
promoted to int in variadic functions. Use '%d' instead.
