As Linus pointed out previous attempt did nothing\nuseful, see d81269fecb8ce (\"io_uring: fix provide_buffers sign extension\").\n\nDo that with help of check_<op>_overflow helpers. And fix struct\nio_provide_buf::len type, as it doesn't make much sense to keep it\nsigned."

Como Linus se\u00f1al\u00f3 que el intento anterior no hizo nada \u00fatil, consulte d81269fecb8ce (\"io_uring: corrige la extensi\u00f3n de signo provide_buffers\"). Haga esto con la ayuda de los ayudantes check__overflow. Y corrija el tipo struct io_provide_buf::len, ya que no tiene mucho sentido mantenerlo firmado."
