    Pull UBI/UBIFS updates from Richard Weinberger:
     "This pull request contains:
    
       - Fixes for both UBI and UBIFS
       - overlayfs support (O_TMPFILE, RENAME_WHITEOUT/EXCHANGE)
       - Code refactoring for the upcoming MLC support"
    
    [ Ugh, we just got rid of the "rename2()" naming for the extended rename
      functionality. And this re-introduces it in ubifs with the cross-
      renaming and whiteout support.
    
      But rather than do any re-organizations in the merge itself, the
      naming can be cleaned up later ]
