List-Id: Linux MTD discussion mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Is there some reason that the mtd and mtdblock drivers do not use ECC when the backing device is nand with ECC enabled? I guess that kind of sums up my question. If the answer is no, I am thinking of patching them so that they do use ECC when available. I suppose you could run into problems if the backing device were a concatenation of ECC and non-ECC devices, but that could probably be detected either on open or at each page read/write. Thanks in advance, David Daney.
