Otherwise an attempt to use FITRIM would stop after hitting the first dm region that didn't support discards. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
