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. Fixes: 636e1970fd7d ("debugobjects: Use global free list in free_object()") Suggested-by: Waiman Long <longman@redhat.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Yang Shi <yang.shi@linux.alibaba.com> Acked-by: Waiman Long <longman@redhat.com> Link: https://lkml.kernel.org/r/20180222155335.1647466-1-arnd@arndb.de
