Subject: [PATCH 1/1] Drivers: hv: use kmalloc_array() instead of kmalloc()
Date: Fri, 21 Nov 2025 11:10:41 +0800 [thread overview]
Message-ID: <20251121031041.56619-1-13875017792@163.com> (raw)
From: Gongwei Li <ligongwei@kylinos.cn>
Replace kmalloc() with kmalloc_array() to prevent potential
overflow, as recommended in Documentation/process/deprecated.rst.
