The patch below does the following cleanups for the NTFS code:
- remove three currently unused global functions
- make several functions and variables static (yes, I've read the
comment before ntfs_readpage before making it static - but I couldn't
see it being actually true)
Is this patch OK or does it conflict with your future plans for the NTFS
code?
