Subject: [PATCH] mm/compaction: Remove some useless code in compact_zone()
Date: Wed, 14 Oct 2020 15:23:49 +0800 [thread overview]
Message-ID: <20201014072349.34494-1-yanfei.xu@windriver.com> (raw)
From: Yanfei Xu <yanfei.xu@windriver.com>
start_pfn has been declared at the begin of compact_zone(), it's
no need to declare it again. And remove an useless semicolon.
