+Subject: [PATCH 1/9] Fix issue with sysfs name comparisons.
+
+It turns out that cdev_name_equal() is used
+by dlist_find_custom() to compare sysfs
+entry names to ones already seen. But it was
+comparing using the length of the shortest string
+as a maximum, so when it compared, for example,
+"eth1" and "eth10", it thought they were the same.
+So now just return failure if the strings
+aren't the same length, else go ahead and
+compare them.
