From 1c52e6d0681020e2272c0cbce270dd91a215e7d3 Mon Sep 17 00:00:00 2001 From: Yafang Shao Date: Mon, 13 May 2019 17:22:40 -0700 Subject: [PATCH] mm/page_alloc.c: remove unnecessary parameter in rmqueue_pcplist Because rmqueue_pcplist() is only called when order is 0, we don't need to use order as a parameter.
