como veo que esta un poco largo el Changelog del 2.6.15 entonces coloco esto
Cita: NTFS: The big ntfs write(2) rewrite has arrived. We now implement our own
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.
en resumen que se puede escribir pero NO se pueden crear archivos, eso creo, tambien hay otra opcion denominada
shared subtrees que hasta ahroa estoy investiando de que trata pero es relacionada con el orden jerarquico del FS en Linux...
saludos
