I see that there are several places of hfs_find_exit() calls in hfs_fill_super(). Maybe, it makes sense to move the hfs_find_exit() call to the end of the hfs_fill_super()? In this case we could process this activity of resources freeing into one place. I mean line 449 in the source code (failure case).
