    Found it. It was a stupid mistake. I made the get_sb function return
    the same superblock when it was still get_sb_nodev. When I switched it
    to the proper get_sb_single I forgot to remove the code that returned
    the old sb so it wasn't calling get_sb_single to increase the sb's usage
    count. Doh!
