      ubifs: fix memory corruption in super.c · b1d6590d
      Heiko Schocher authored
      In list "super_blocks" ubifs collects allocated super_block
      structs. U-Boot frees on unmount the allocated struct,
      so the pointer stored in this list is free after the umount.
      On a new ubifs mount, the new allocated super_block struct
      get inserted into the super_blocks list ... which contains
      now a freed pointer, and the list_add_tail() corrupts the
      freed memory ...
      2 solutions are possible:
      - remove the super_block from the super_blocks list
        on umount
      - as U-Boot does not use the super_blocks list ...
        remove it complete for U-Boot.
      Both solutions should not introduce problems for porting
      to newer linux version, so this patch removes the unused
      super_blocks list, as it saves code size and execution
