From 6eba06c395f72e43505b21f073275bd071782552 Mon Sep 17 00:00:00 2001 From: Daniel Neukomm Date: Tue, 11 Aug 2009 11:33:23 +0300 Subject: mkfs.ubifs: correct devtable increment handling With the device table one can add /dev entries to the root file system image. The device table file contains among others the fields minor, start, increment and count. If there is an entry with minor=0 start=0 increment=32 and count=4 the mkfs.ubifs makes 128 device entries, with minor numbers from 0 to 127. The correct version makes 4 entries with minor number 0,32,64,96. /dev/mtd c 640 0 0 90 0 0 2 7 This gives 14 devices /dev/mtdXX instead of 7 devices. Due to this error mtd_debug info /dev/mtd3 delivers the information of /dev/mtd1 instead of.
