Merge git://github.com/Paragon-Software-Group/linux-ntfs3 

Merge NTFSv3 filesystem from Konstantin Komarov:
 "This patch adds NTFS Read-Write driver to fs/ntfs3.

  Having decades of expertise in commercial file systems development and
  huge test coverage, we at Paragon Software GmbH want to make our
  contribution to the Open Source Community by providing implementation
  of NTFS Read-Write driver for the Linux Kernel.

  This is fully functional NTFS Read-Write driver. Current version works
  with NTFS (including v3.1) and normal/compressed/sparse files and
  supports journal replaying.

  We plan to support this version after the codebase once merged, and
  add new features and fix bugs. For example, full journaling support
  over JBD will be added in later updates"

NTFS3

=====





Summary and Features

====================



NTFS3 is fully functional NTFS Read-Write driver. The driver works with

NTFS versions up to 3.1, normal/compressed/sparse files

and journal replaying. File system type to use on mount is 'ntfs3'.



- This driver implements NTFS read/write support for normal, sparse and

  compressed files.

- Supports native journal replaying;

- Supports extended attributes

	Predefined extended attributes:

	- 'system.ntfs_security' gets/sets security

			descriptor (SECURITY_DESCRIPTOR_RELATIVE)

	- 'system.ntfs_attrib' gets/sets ntfs file/dir attributes.

		Note: applied to empty files, this allows to switch type between

		sparse(0x200), compressed(0x800) and normal;

- Supports NFS export of mounted NTFS volumes.



Mount Options

=============



The list below describes mount options supported by NTFS3 driver in addition to

generic ones.



===============================================================================



nls=name		This option informs the driver how to interpret path

			strings and translate them to Unicode and back. If

			this option is not set, the default codepage will be

			used (CONFIG_NLS_DEFAULT).

			Examples:

				'nls=utf8'



uid=

gid=

umask=			Controls the default permissions for files/directories created

			after the NTFS volume is mounted.



fmask=

dmask=			Instead of specifying umask which applies both to

			files and directories, fmask applies only to files and

			dmask only to directories.



nohidden		Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN)

			attribute will not be shown under Linux.



sys_immutable		Files with the Windows-specific SYSTEM

			(FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system

			immutable files.



discard			Enable support of the TRIM command for improved performance

			on delete operations, which is recommended for use with the

			solid-state drives (SSD).



force			Forces the driver to mount partitions even if 'dirty' flag

			(volume dirty) is set. Not recommended for use.



sparse			Create new files as "sparse".



showmeta		Use this parameter to show all meta-files (System Files) on

			a mounted NTFS partition.

			By default, all meta-files are hidden.



prealloc		Preallocate space for files excessively when file size is

			increasing on writes. Decreases fragmentation in case of

			parallel write operations to different files.



no_acs_rules		"No access rules" mount option sets access rights for

			files/folders to 777 and owner/group to root. This mount

			option absorbs all other permissions:

			- permissions change for files/folders will be reported

				as successful, but they will remain 777;

			- owner/group change will be reported as successful, but

				they will stay as root



acl			Support POSIX ACLs (Access Control Lists). Effective if

			supported by Kernel. Not to be confused with NTFS ACLs.

			The option specified as acl enables support for POSIX ACLs.



noatime			All files and directories will not update their last access

			time attribute if a partition is mounted with this parameter.

			This option can speed up file system operation.



===============================================================================



ToDo list

=========



- Full journaling support (currently journal replaying is supported) over JBD.
