From a52149f129bd161818fd7a0b6450aaa30a2cbd77 Mon Sep 17 00:00:00 2001 From: John Hubbard Date: Mon, 10 Jul 2017 15:49:41 -0700 Subject: [PATCH] mm/memory_hotplug.c: remove unused local zone_type from __remove_zone() __remove_zone() sets up up zone_type, but never uses it for anything. This does not cause a warning, due to the (necessary) use of -Wno-unused-but-set-variable. However, it's noise, so just delete it.
