Added to the ext4 patch queue with a slight adjustment in the patch
commit for readability issues:

   When creating a new ext4_prealloc_space structure, we have to
   initialize its list_head pointers before we add them to any prealloc
   lists.  Otherwise, with list debug enabled, we will get list
   corruption warnings.
