From: Miaohe Lin Date: Thu, 3 Aug 2023 11:49:34 +0000 (+0800) Subject: mm/page_alloc: remove unneeded variable base X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c1dc69e6ce65d95e3d4d080868c3007f1a6fc4fe;p=tomoyo%2Ftomoyo-test1.git mm/page_alloc: remove unneeded variable base Since commit 5d0a661d808f ("mm/page_alloc: use only one PCP list for THP-sized allocations"), local variable base is just as same as order. So remove it. No functional change intended.
