I think the right fix should be to rewrite proc_create_single() as a static inline function that calls proc_create_single_data() when CONFIG_PROC_FS is selected and just returns NULL otherwise. > static int proc_eeh_show(struct seq_file *m, void *v) > { > if (!eeh_enabled()) { > @@ -1662,6 +1663,7 @@ static int proc_eeh_show(struct seq_file *m, void *v) > > return 0; > } > +#endif > > #ifdef CONFIG_DEBUG_FS > static int eeh_enable_dbgfs_set(void *data, u64 val) > Christophe
