From 94780d4de2e9339ab93df63420db70f11882634d Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 4 Dec 2007 21:36:12 +0200 Subject: UBI: bugfix: allocate mandatory EBs first First allocate the necessary eraseblocks, then the optional ones. Otherwise it allocates all PEBs for bad EB handling, and fails on then following EBA LEB allocation.
