When the new option --unused-fast is used, clusters which appear as wiped
are not written again. This is useful for avoiding virtual partitions to
be extended to their full size.

ntfsfallocate is the equivalent of fallocate(1) :
Usage : ntfsfallocate [-n] [-p] [-o offset] -l length filename
For now, it is only released as a quarantined ntfsprogs because it can
produce configurations which cause subsequent updates of the file by
Windows to hang.
Distributions have complained about releasing a non-functional ntfsck.
Actually, ntfsck and a few other developer-oriented utilities were not
meant to be released by distributions and are only compiled in if the
configure option --enable-extra is set, and, for some reason, this
option is set by most distributions.
In order to get distributions to not complain, though making the source
code available for candidate developers to improve it, the non functional
or developer-oriented utilities (ntfsck, ntfsdump_logfile, ntfsmftalloc
and ntfsmove) are now only compiled in if the configure option
--enable-quarantined is set.
The ntfsprogs used to return failure when option --version or --help
was used, and this has triggered complains from distribution packagers
who use these options in packaging scripts.
With this patch, success is returned (same behavior as gcc).
When the partition is resized, the global bitmap size is adjusted accordingly,
however so far the new size was not set into the parent index (only minor
consequences).
The ioctl() function is not implemented in the Windows variant. By forcing
a negative apparent return, an alternative is triggered to get the
partition size which is normally obtained from an ioctl().
In some rare situations relocated runlists are longer than the original
ones and do not fit into the same extent. When this happens the runlist
updating is delayed and done globally. Be sure to use the updated global
bitmap for making the needed allocations.
X509 certificates have a purpose field restricting what the certificate
can be used for, and EFS encryption is such a purpose. Allow EFS encryption
to be at any position in the list.
When ntfsclone'ing to a file, the target file was truncated to the volume
size. This is not useful on file systems which support sparse files. In
the case of ntfs-3g this leads to prevent optimizations specific to
appending data. So when a sparse output file is detected, it is emptied
to benefit from subsequent appending of data.
The upcoming libgrypt-1.6 drops the "module" interface which was used
by ntfsdecrypt for decrypting files which were encrypted with the "DESX"
algorithm. This algorithm is a Microsoft variant of DES with a key size
of 128 bits, and is not natively supported by libgrypt. The module interface
made possible to declare an external algorithm so that all the encryption
modes could be processed the same way whether the algorithm was internal
or external.
This patch makes DESX a specific case, so that the module interface is
not needed any more. It is compatible with current libgrypt and upcoming
libgrypt-1.6
