Subject: [PATCH 2/7] lib/mpi: use kcalloc in mpi_resize
Date: Wed, 12 May 2021 22:04:09 +0800 [thread overview]
Message-ID: <1620828254-25545-3-git-send-email-herbert.tencent@gmail.com> (raw)
In-Reply-To: <1620828254-25545-1-git-send-email-herbert.tencent@gmail.com>
From: Hongbo Li <herberthbli@tencent.com>
We should set the additional space to 0 in mpi_resize().
So use kcalloc() instead of kmalloc_array().
