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 time.
