Subject: [PATCH 3/4] drivers/scsi/snic/snic_trc: Use vzalloc instead of vmalloc+memset
Date: Wed, 1 Aug 2018 21:26:15 +0800 [thread overview]
Message-ID: <1533129976-51930-4-git-send-email-zhongjiang@huawei.com> (raw)
In-Reply-To: <1533129976-51930-1-git-send-email-zhongjiang@huawei.com>
The vzmalloc is better than vmalloc+memset, so replace them.
