-ChangeLog
-=========
-
-2.1.30:
-	- Fix writev() (it kept writing the first segment over and over again
-	  instead of moving onto subsequent segments).
-	- Fix crash in ntfs_mft_record_alloc() when mapping the new extent mft
-	  record failed.
-2.1.29:
-	- Fix a deadlock when mounting read-write.
-2.1.28:
-	- Fix a deadlock.
-2.1.27:
-	- Implement page migration support so the kernel can move memory used
-	  by NTFS files and directories around for management purposes.
-	- Add support for writing to sparse files created with Windows XP SP2.
-	- Many minor improvements and bug fixes.
-2.1.26:
-	- Implement support for sector sizes above 512 bytes (up to the maximum
-	  supported by NTFS which is 4096 bytes).
-	- Enhance support for NTFS volumes which were supported by Windows but
-	  not by Linux due to invalid attribute list attribute flags.
-	- A few minor updates and bug fixes.
-2.1.25:
-	- Write support is now extended with write(2) being able to both
-	  overwrite existing file data and to extend files.  Also, if a write
-	  to a sparse region occurs, write(2) will fill in the hole.  Note,
-	  mmap(2) based writes still do not support writing into holes or
-	  writing beyond the initialized size.
-	- Write support has a new feature and that is that truncate(2) and
-	  open(2) with O_TRUNC are now implemented thus files can be both made
-	  smaller and larger.
-	- Note: Both write(2) and truncate(2)/open(2) with O_TRUNC still have
-	  limitations in that they
-	  - only provide limited support for highly fragmented files.
-	  - only work on regular, i.e. uncompressed and unencrypted files.
-	  - never create sparse files although this will change once directory
-	    operations are implemented.
-	- Lots of bug fixes and enhancements across the board.
-2.1.24:
-	- Support journals ($LogFile) which have been modified by chkdsk.  This
-	  means users can boot into Windows after we marked the volume dirty.
-	  The Windows boot will run chkdsk and then reboot.  The user can then
-	  immediately boot into Linux rather than having to do a full Windows
-	  boot first before rebooting into Linux and we will recognize such a
-	  journal and empty it as it is clean by definition.
-	- Support journals ($LogFile) with only one restart page as well as
-	  journals with two different restart pages.  We sanity check both and
-	  either use the only sane one or the more recent one of the two in the
-	  case that both are valid.
-	- Lots of bug fixes and enhancements across the board.
-2.1.23:
-	- Stamp the user space journal, aka transaction log, aka $UsnJrnl, if
-	  it is present and active thus telling Windows and applications using
-	  the transaction log that changes can have happened on the volume
-	  which are not recorded in $UsnJrnl.
-	- Detect the case when Windows has been hibernated (suspended to disk)
-	  and if this is the case do not allow (re)mounting read-write to
-	  prevent data corruption when you boot back into the suspended
-	  Windows session.
-	- Implement extension of resident files using the normal file write
-	  code paths, i.e. most very small files can be extended to be a little
-	  bit bigger but not by much.
-	- Add new mount option "disable_sparse".  (See list of mount options
-	  above for details.)
-	- Improve handling of ntfs volumes with errors and strange boot sectors
-	  in particular.
-	- Fix various bugs including a nasty deadlock that appeared in recent
-	  kernels (around 2.6.11-2.6.12 timeframe).
-2.1.22:
-	- Improve handling of ntfs volumes with errors.
-	- Fix various bugs and race conditions.
-2.1.21:
-	- Fix several race conditions and various other bugs.
-	- Many internal cleanups, code reorganization, optimizations, and mft
-	  and index record writing code rewritten to fit in with the changes.
-	- Update Documentation/filesystems/ntfs.txt with instructions on how to
-	  use the Device-Mapper driver with NTFS ftdisk/LDM raid.
-2.1.20:
-	- Fix two stupid bugs introduced in 2.1.18 release.
-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
-	  lookup code.
-2.1.17:
-	- Fix bugs in mount time error code paths.
-2.1.16:
-	- Implement access time updates (including mtime and ctime).
-	- Implement fsync(2), fdatasync(2), and msync(2) system calls.
-	- Enable the readv(2) and writev(2) system calls.
-	- Enable access via the asynchronous io (aio) API by adding support for
-	  the aio_read(3) and aio_write(3) functions.
-2.1.15:
-	- Invalidate quotas when (re)mounting read-write.
-	  NOTE:  This now only leave user space journalling on the side.  (See
-	  note for version 2.1.13, below.)
-2.1.14:
-	- Fix an NFSd caused deadlock reported by several users.
-2.1.13:
-	- Implement writing of inodes (access time updates are not implemented
-	  yet so mounting with -o noatime,nodiratime is enforced).
-	- Enable writing out of resident files so you can now overwrite any
-	  uncompressed, unencrypted, nonsparse file as long as you do not
-	  change the file size.
-	- Add housekeeping of ntfs system files so that ntfsfix no longer needs
-	  to be run after writing to an NTFS volume.
-	  NOTE:  This still leaves quota tracking and user space journalling on
-	  the side but they should not cause data corruption.  In the worst
-	  case the charged quotas will be out of date ($Quota) and some
-	  userspace applications might get confused due to the out of date
-	  userspace journal ($UsnJrnl).
-2.1.12:
-	- Fix the second fix to the decompression engine from the 2.1.9 release
-	  and some further internals cleanups.
-2.1.11:
-	- Driver internal cleanups.
-2.1.10:
-	- Force read-only (re)mounting of volumes with unsupported volume
-	  flags and various cleanups.
-2.1.9:
-	- Fix two bugs in handling of corner cases in the decompression engine.
-2.1.8:
-	- Read the $MFT mirror and compare it to the $MFT and if the two do not
-	  match, force a read-only mount and do not allow read-write remounts.
-	- Read and parse the $LogFile journal and if it indicates that the
-	  volume was not shutdown cleanly, force a read-only mount and do not
-	  allow read-write remounts.  If the $LogFile indicates a clean
-	  shutdown and a read-write (re)mount is requested, empty $LogFile to
-	  ensure that Windows cannot cause data corruption by replaying a stale
-	  journal after Linux has written to the volume.
-	- Improve time handling so that the NTFS time is fully preserved when
-	  converted to kernel time and only up to 99 nano-seconds are lost when
-	  kernel time is converted to NTFS time.
-2.1.7:
-	- Enable NFS exporting of mounted NTFS volumes.
-2.1.6:
-	- Fix minor bug in handling of compressed directories that fixes the
-	  erroneous "du" and "stat" output people reported.
-2.1.5:
-	- Minor bug fix in attribute list attribute handling that fixes the
-	  I/O errors on "ls" of certain fragmented files found by at least two
-	  people running Windows XP.
-2.1.4:
-	- Minor update allowing compilation with all gcc versions (well, the
-	  ones the kernel can be compiled with anyway).
-2.1.3:
-	- Major bug fixes for reading files and volumes in corner cases which
-	  were being hit by Windows 2k/XP users.
-2.1.2:
-	- Major bug fixes alleviating the hangs in statfs experienced by some
-	  users.
-2.1.1:
-	- Update handling of compressed files so people no longer get the
-	  frequently reported warning messages about initialized_size !=
-	  data_size.
-2.1.0:
-	- Add configuration option for developmental write support.
-	- Initial implementation of file overwriting. (Writes to resident files
-	  are not written out to disk yet, so avoid writing to files smaller
-	  than about 1kiB.)
-	- Intercept/abort changes in file size as they are not implemented yet.
-2.0.25:
-	- Minor bugfixes in error code paths and small cleanups.
-2.0.24:
-	- Small internal cleanups.
-	- Support for sendfile system call. (Christoph Hellwig)
-2.0.23:
-	- Massive internal locking changes to mft record locking. Fixes
-	  various race conditions and deadlocks.
-	- Fix ntfs over loopback for compressed files by adding an
-	  optimization barrier. (gcc was screwing up otherwise ?)
-	Thanks go to Christoph Hellwig for pointing these two out:
-	- Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs().
-	- Fix ntfs_free() for ia64 and parisc.
-2.0.22:
-	- Small internal cleanups.
-2.0.21:
-	These only affect 32-bit architectures:
-	- Check for, and refuse to mount too large volumes (maximum is 2TiB).
-	- Check for, and refuse to open too large files and directories
-	  (maximum is 16TiB).
-2.0.20:
-	- Support non-resident directory index bitmaps. This means we now cope
-	  with huge directories without problems.
-	- Fix a page leak that manifested itself in some cases when reading
-	  directory contents.
-	- Internal cleanups.
-2.0.19:
-	- Fix race condition and improvements in block i/o interface.
-	- Optimization when reading compressed files.
-2.0.18:
-	- Fix race condition in reading of compressed files.
-2.0.17:
-	- Cleanups and optimizations.
-2.0.16:
-	- Fix stupid bug introduced in 2.0.15 in new attribute inode API.
-	- Big internal cleanup replacing the mftbmp access hacks by using the
-	  new attribute inode API instead.
-2.0.15:
-	- Bug fix in parsing of remount options.
-	- Internal changes implementing attribute (fake) inodes allowing all
-	  attribute i/o to go via the page cache and to use all the normal
-	  vfs/mm functionality.
-2.0.14:
-	- Internal changes improving run list merging code and minor locking
-	  change to not rely on BKL in ntfs_statfs().
-2.0.13:
-	- Internal changes towards using iget5_locked() in preparation for
-	  fake inodes and small cleanups to ntfs_volume structure.
-2.0.12:
-	- Internal cleanups in address space operations made possible by the
-	  changes introduced in the previous release.
-2.0.11:
-	- Internal updates and cleanups introducing the first step towards
-	  fake inode based attribute i/o.
-2.0.10:
-	- Microsoft says that the maximum number of inodes is 2^32 - 1. Update
-	  the driver accordingly to only use 32-bits to store inode numbers on
-	  32-bit architectures. This improves the speed of the driver a little.
-2.0.9:
-	- Change decompression engine to use a single buffer. This should not
-	  affect performance except perhaps on the most heavy i/o on SMP
-	  systems when accessing multiple compressed files from multiple
-	  devices simultaneously.
-	- Minor updates and cleanups.
-2.0.8:
-	- Remove now obsolete show_inodes and posix mount option(s).
-	- Restore show_sys_files mount option.
-	- Add new mount option case_sensitive, to determine if the driver
-	  treats file names as case sensitive or not.
-	- Mostly drop support for short file names (for backwards compatibility
-	  we only support accessing files via their short file name if one
-	  exists).
-	- Fix dcache aliasing issues wrt short/long file names.
-	- Cleanups and minor fixes.
-2.0.7:
-	- Just cleanups.
-2.0.6:
-	- Major bugfix to make compatible with other kernel changes. This fixes
-	  the hangs/oopses on umount.
-	- Locking cleanup in directory operations (remove BKL usage).
-2.0.5:
-	- Major buffer overflow bug fix.
-	- Minor cleanups and updates for kernel 2.5.12.
-2.0.4:
-	- Cleanups and updates for kernel 2.5.11.
-2.0.3:
-	- Small bug fixes, cleanups, and performance improvements.
-2.0.2:
-	- Use default fmask of 0177 so that files are no executable by default.
-	  If you want owner executable files, just use fmask=0077.
-	- Update for kernel 2.5.9 but preserve backwards compatibility with
-	  kernel 2.5.7.
-	- Minor bug fixes, cleanups, and updates.
-2.0.1:
-	- Minor updates, primarily set the executable bit by default on files
-	  so they can be executed.
-2.0.0:
-	- Started ChangeLog.
