+From: Jan Kara <jack@suse.cz>
+Subject: udf: Use device size when drive reported bogus number of written blocks
+References: bnc#501663
+Patch-mainline: 2.6.31
+
+Some drives report 0 as the number of written blocks when there are some blocks
+recorded. Use device size in such case so that we can automagically mount such
+media.
