Subject: [PATCH 1/3] mm/vmscan: not necessary to re-init the list for each iteration
Date: Tue, 26 Apr 2022 02:17:41 +0000 [thread overview]
Message-ID: <20220426021743.21007-1-richard.weiyang@gmail.com> (raw)
node_page_list is defined with LIST_HEAD and be cleaned until
list_empty.
So it is not necessary to re-init it again.
