Subject: [PATCH 01/10] mm/page_alloc: remove unlikely macro on free_one_page()
Date: Fri, 4 Jul 2014 16:57:46 +0900 [thread overview]
Message-ID: <1404460675-24456-2-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1404460675-24456-1-git-send-email-iamjoonsoo.kim@lge.com>
Isolation is really rare case so !is_migrate_isolate() is
likely case. Remove unlikely macro.
