From 238050eeebb0389ecdc5fe3c016194b287a30100 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 19 Feb 2008 17:17:44 +0200 Subject: Remove redundant tests Sorry for this mess in the history, but I hope this is the last ugly commit. I accidentally copies the tests from mtd-utils.git/tests/ubi-tests/ to here. Remove them.
