Why? > + argv_free(helper_argv); > + goto fail_dropcount; > + } > + > + retval = call_usermodehelper_exec(sub_info, UMH_WAIT_EXEC); I do not really like another argv_free() here... How about retval = -ENOMEM; info = call_usermodehelper_setup(...); if (info) retval = call_usermodehelper_fns(...); argv_free(); ?
