Hmm. I think this is wrong. Don't we need to remove the fail_at_unmount
file *before* removing the kobject?

So, we'd need to actually call sysfs_remove_file() before actually
deleting the m_error_kobj.

I am honestly not sure if kobject_del would clean up any attributes
added there, but I think that's the right thing to do here?!

Cheers.
