Actually, this wasn't quite fixed.  Here's a fix which I'll include in
the ext4 tree....

Subject: [PATCH] ext4: return an error if kset_create_and_add fails in
 ext4_init_fs()

In the very unlikely case that kset_create_and_add() fails when the
ext4.ko module is being loaded (or during kernel startup) set err so
that it's clear that the module load failed.
