From 81fefdf2efa599df9e8b362bb04d5fe5a83bc353 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 3 Feb 2012 10:14:12 +0200 Subject: [PATCH] mtd: spear_smi: initialize writebufsize 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 writebufsize to the flash page size because it is the maximum amount of data it writes at a time.
