706 | Although most flash chips have an erase size too large to be useful | |

708 | on RAM chips in this manner. This block device is a user of MTD | |
709 | devices performing that function. | |

713 | (although JFFS and JFFS2 don't actually use any of the functionality | |
714 | of the mtdblock device). | |
715 | ||
716 | Later, it may be extended to perform read/erase/modify/write cycles | |
