It applies instead of the previous patch in that series, that is after
the 9 patches before it.  I don't think hfsplus has issue you mentioned
in that other thread, not by design but more by accident due to:

 - not checking the dirty bits anymore as it doesn't implement the
   fdatasync optimization.
 - hfsplus_write_inode first calling hfsplus_ext_write_extent before
   setting the catalog dirty bit, with hfsplus_ext_write_extent always
   locking and unlocking a mutex and thus providing the required memory
   barrier.
