Merge tag 'core-debugobjects-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull debugobjects updates from Thomas Gleixner: "A small set of updates for debug objects: - Make all debug object descriptors constant. There is no reason to have them writeable. - Free the per CPU object pool after CPU unplug to avoid memory waste" * tag 'core-debugobjects-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: debugobjects: Free per CPU pool after CPU unplug treewide: Make all debug_obj_descriptors const debugobjects: Allow debug_obj_descr to be const
