Subject: mm/vmscan: not necessary to re-init the list for each iteration
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=048f6e1a427ee9cddf62f9b3766372c69846fa4f;p=linux.git

mm/vmscan: not necessary to re-init the list for each iteration

node_page_list is defined with LIST_HEAD and be cleaned until
list_empty.

So it is not necessary to re-init it again.

[akpm@linux-foundation.org: remove unneeded braces]
