SPDX-License-Identifier: GPL-2.0 + +===== +NTFS3 +===== + + +Summary and Features +==================== + +NTFS3 is fully functional NTFS Read-Write driver.

If + this option is not set, the default codepage will be + used (CONFIG_NLS_DEFAULT). + Examples: + 'nls=utf8' + +nls_alt=name This option extends "nls". It will be used to translate + path string to Unicode if primary nls failed. + Examples: + 'nls_alt=cp1251' + +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. + + +References +========== +https://www.paragon-software.com/home/ntfs-linux-professional/ + - Commercial version of the NTFS driver for Linux. + +almaz.alexandrovich@paragon-software.com + - Direct e-mail address for feedback and requests on the NTFS3 implementation. + diff --git a/fs/ntfs3/Kconfig b/fs/ntfs3/Kconfig new file mode 100644 index 000000000000..92a9c68008c8 --- /dev/null +++ b/fs/ntfs3/Kconfig @@ -0,0 +1,23 @@ +# SPDX-License-Identifier: GPL-2.0-only +config NTFS3_FS + tristate "NTFS Read-Write file system support" + select NLS + help + Windows OS native file system (NTFS) support up to NTFS version 3.1. + + Y or M enables the NTFS3 driver with full features enabled (read, + write, journal replaying, sparse/compressed files support). + File system type to use on mount is "ntfs3".
