    NTFS: The big ntfs write(2) rewrite has arrived. We now implement our own · 98b27036
    Anton Altaparmakov authored
          file operations ->write(), ->aio_write(), and ->writev() for regular
          files.  This replaces the old use of generic_file_write(), et al and
          the address space operations ->prepare_write and ->commit_write.
          This means that both sparse and non-sparse (unencrypted and
          uncompressed) files can now be extended using the normal write(2)
          code path.  There are two limitations at present and these are that
          we never create sparse files and that we only have limited support
          for highly fragmented files, i.e. ones whose data attribute is split
          across multiple extents.   When such a case is encountered,
          EOPNOTSUPP is returned.
