A concurrent read of the monmap debugfs\nfile can enter monmap_show() after ceph_monc_stop() has freed\nmonc->monmap, triggering a use-after-free.\n\nRemove the debugfs files before stopping the OSD and monitor clients.\ndebugfs_remove() drains active handlers and prevents new accesses, so\nthe debugfs callbacks can no longer race the rest of client
