Si blk-wbt est\u00e1 habilitado por defecto, el rendimiento de escritura en RAID es bastante bajo, ya que todas las E/S son limitadas por wbt de los discos subyacentes, debido a que se ignora el indicador REQ_IDLE. Resulta que este comportamiento existe desde la introducci\u00f3n de blk-wbt.

REQ_NOWAIT tampoco se debe borrar, ya que la E/S esperar\u00e1 en lugar de fallar directamente en los discos subyacentes.
