Move disabling the elevator and freeing the scheduler tags\nto the end of del_gendisk instead of doing that work in disk_release and\nblk_cleanup_queue to avoid a use after free on q->tag_set from\ndisk_release as the tag_set might not be alive at that point.\n\nMove the blk_qos_exit call as well, as it just depends on the elevator\nexit and would be the only reason to keep the not exactly cheap queue\nfreeze in disk_release."

Mueva la desactivaci\u00f3n del elevador y la liberaci\u00f3n de las etiquetas del programador al final de del_gendisk en lugar de hacer ese trabajo en disk_release y blk_cleanup_queue para evitar un use-after-free en q->tag_set desde disk_release ya que tag_set podr\u00eda no estar activo en ese punto. Mueva tambi\u00e9n la llamada blk_qos_exit, ya que solo depende de la salida del elevador y ser\u00eda la \u00fanica raz\u00f3n para mantener la congelaci\u00f3n de la cola no exactamente barata en disk_release."
