From 04148187aa9df3626168f7429d2287997787e387 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 22 Feb 2018 16:52:58 +0100 Subject: debugobjects: Fix debug_objects_freed accounting The removal of the batched object freeing has caused the debug_objects_freed to become read-only, and the reading is inside an ifdef, so gcc warns that it is completely unused without CONFIG_DEBUG_FS: lib/debugobjects.c:71:14: error: 'debug_objects_freed' defined but not used [-Werror=unused-variable] Assuming we are still interested in this number, this adds back code to keep track of the freed objects.
