From 7fa33ac0a7e24a1b8bd71be5c47a17423c62fbda Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Thu, 16 Dec 2010 23:42:18 +0100 Subject: mtd: initialize writebufsize in the MTD object of a partition Propagate the writebufsize to the partition's MTD object so that UBI can set correct value for it's minimal I/O size using the writebufsize field of MTD object of the partition. By previous patches we added proper writebufsize field initialization. Next patch can now change UBI to use this field for setting the minimal I/O size.
