Subject: [PATCH v2 1/5] hugetlbfs: use helper macro SZ_1{K,M}
Date: Tue, 26 Jul 2022 22:29:14 +0800	[thread overview]
Message-ID: <20220726142918.51693-2-linmiaohe@huawei.com> (raw)
In-Reply-To: <20220726142918.51693-1-linmiaohe@huawei.com>

Use helper macro SZ_1K and SZ_1M to do the size conversion. Minor
readability improvement.
