From a4585d8f7a51e32175eed9cdcb85bbe7df84e035 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 3 Feb 2012 09:53:28 +0200 Subject: mtd: lart: initialize writebufsize commit fcc44a07dae0af16e84e93425fc8afe642ddc603 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 writebufsize to 4 because this drivers writes at max 4 bytes at a time.
