Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
2.1.19:
- Minor bugfix in handling of the default upcase table.
- Many internal cleanups and improvements. Many thanks to Linus
Torvalds and Al Viro for the help and advice with the sparse
annotations and cleanups.
2.1.18:
- Fix scheduling latencies at mount time. (Ingo Molnar)
- Fix endianness bug in a little traversed portion of the attribute

- Enable the code for setting the NT4 compatibility flag when we start
making NTFS 1.2 specific modifications.
2.1.19-WIP
2.1.19 - Many cleanups, improvements, and a minor bug fix.
- Update ->setattr (fs/ntfs/inode.c::ntfs_setattr()) to refuse to
change the uid, gid, and mode of an inode as we do not support NTFS
......@@ -34,6 +34,26 @@ ToDo/Notes:
- Update ->truncate (fs/ntfs/inode.c::ntfs_truncate()) to check if the
inode size has changed and to only output an error if so.
- Rename fs/ntfs/attrib.h::attribute_value_length() to ntfs_attr_size().
- Add le{16,32,64} as well as sle{16,32,64} data types to
fs/ntfs/types.h.
- Change ntfschar to be le16 instead of u16 in fs/ntfs/types.h.
- Add le versions of VCN, LCN, and LSN called leVCN, leLCN, and leLSN,
respectively, to fs/ntfs/types.h.
- Update endianness conversion macros in fs/ntfs/endian.h to use the
new types as appropriate.
- Do proper type casting when using sle64_to_cpup() in fs/ntfs/dir.c
and index.c.
- Add leMFT_REF data type to fs/ntfs/layout.h.
- Update all NTFS header files with the new little endian data types.
Affected files are fs/ntfs/layout.h, logfile.h, and time.h.
- Do proper type casting when using ntfs_is_*_recordp() in
fs/ntfs/logfile.c, mft.c, and super.c.
- Fix all the sparse bitwise warnings. Had to change all the enums
storing little endian values to #defines because we cannot set enums
to be little endian so we had lots of bitwise warnings from sparse.
- Fix a bug found by the new sparse bitwise warnings where the default
upcase table was defined as a pointer to wchar_t rather than ntfschar
in fs/ntfs/ntfs.h and super.c.
2.1.18 - Fix scheduling latencies at mount time as well as an endianness bug.
