If anyone has any objections, please let me know. ------------------ From: Artem Bityutskiy commit 82c4c58d6f1a78e8de875272a19ab9220b8066aa 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.
