Subject: [PATCH v18 10/32] mm/compaction: rename compact_deferred as compact_should_defer
Date: Mon, 24 Aug 2020 20:54:43 +0800 [thread overview]
Message-ID: <1598273705-69124-11-git-send-email-alex.shi@linux.alibaba.com> (raw)
In-Reply-To: <1598273705-69124-1-git-send-email-alex.shi@linux.alibaba.com>
The compact_deferred is a defer suggestion check, deferring action does in
defer_compaction not here. so, better rename it to avoid confusing.
