From 19d3cf9de1c72fd1adaa1d68aa40d74a35688404 Mon Sep 17 00:00:00 2001 From: Yanfei Xu Date: Mon, 14 Dec 2020 19:12:39 -0800 Subject: mm/compaction: rename 'start_pfn' to 'iteration_start_pfn' in compact_zone() There are two 'start_pfn' declared in compact_zone() which have different meanings. Rename the second one to 'iteration_start_pfn' to prevent confusion. Also, remove an useless semicolon.
