Subject: [PATCH 11/11] mm/page_alloc: use standard migration target allocation function directly
Date: Mon, 18 May 2020 10:20:57 +0900 [thread overview]
Message-ID: <1589764857-6800-12-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1589764857-6800-1-git-send-email-iamjoonsoo.kim@lge.com>
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
There is no need to make a function in order to call standard migration
target allocation function. Use standard one directly.
