we have code that does static void v9fs_string_sprintf(V9fsString *str, const char *fmt, ...) { va_list ap; int err; v9fs_string_free(str); va_start(ap, fmt); err = vasprintf(&str->data, fmt, ap); BUG_ON(err == -1); va_end(ap); str->size = err; } I guess we should not be using vasprint. What alternatives are available today ? -aneesh
