  Log:
  Revise and improve ntfs_subr.c 1.30: read only a single cluster at a time
  in ntfs_writentvattr_plain and ntfs_readntvattr_plain, and purge the boot
  block from the buffer cache if isn't exactly one cluster long. These two
  changes work around the same buffer cache bug that ntfs_subr.c 1.30 tried
  to, but in a different way. This may decrease throughput by reading smaller
  amounts of data from the disk at a time, but may increase it by avoiding
  bogus writes of clean buffers.
  Problem (re)reported by Karel J. Bosschaart on -current.
