For writes, you'll need to do a read-modify-write sequence on the entire block, after you determine what the proper block is given prior block-skipping. Or better, don't try to use this simplistic mechanism to do writes in the middle of a partition -- use something like ubi that was meant for this. -Scott

When using nand_write_skip_bad, the aligned offset refers to page (not sector or block), so if as I understand , I can read from the start of page the whole relevant data, then modify only the parts which is changed, and then write it again, but the writing is not for the entire block: I will use the nand_write_skip_bad given offset of the start of page, and length will be the unaligned length for the whole data being written (which is part of the entire block).
