    NTFS 2.0.3: Small bug fixes, cleanups, and performance improvements. · eeb382a1

    - Remove some dead code from mft.c.
    - Optimize readpage and read_block functions throughout aops.c so that
      only initialized blocks are read. Non-initialized ones have their
      buffer head mapped, zeroed, and set up to date, without scheduling
      any i/o. Thanks to Al Viro for advice on how to avoid the device i/o.
    Thanks go to Andrew Morton for spotting the below:
    - Fix buglet in allocate_compression_buffers() error code path.
    - Call flush_dcache_page() after modifying page cache page contents in
      ntfs_file_readpage().
    - Check for existence of page buffers throughout aops.c before calling
      create_empty_buffers(). This happens when an I/O error occurs and the
      read is retried. (It also happens once writing is implemented so that
      needed doing anyway but I had left it for later...)
    - Don't BUG_ON() uptodate and/or mapped buffers throughout aops.c in
      readpage and read_block functions. Reasoning same as above (i.e. I/O
      error retries and future write code paths.)
