If anyone has any objections, please let me know. ------------------ From: Artem Bityutskiy commit 71f60fbebf0f18dd4e855335a009efda251b1697 upstream. The writebufsize concept was introduce by commit "0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents the maximum amount of data the device writes to the media at a time. This is an important parameter for UBIFS which is used during recovery and which basically defines how big a corruption caused by a power cut can be. Set it to be equivalent to mtd->writesize because this is the maximum amount of data the driver writes at a time.
