--- Comment #3 from Bernhard M. Wiedemann <gccbmw at lsmod dot de> ---
It seems to be triggered by nvme-cli/cmd_handler.h

#define PLUGIN(name, cmds)                              \
static struct plugin plugin = {                         \
        name                                            \
        .commands = commands                            \
};                                                      \
                                                        \
static void init(void) __attribute__((constructor));    \
static void init(void)                                  \
{                                                       \
        register_extension(&plugin);                    \
}
