 Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
 
+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.

 	- In between ntfs_prepare/commit_write, need exclusion between
-	  simultaneous file extensions. Need perhaps an NInoResizeUnderway()
-	  flag which we can set in ntfs_prepare_write() and clear again in
-	  ntfs_commit_write(). Just have to be careful in readpage/writepage,
-	  as well as in truncate, that we play nice... We might need to have
-	  a data_size field in the ntfs_inode to store the real attribute
-	  length. Also need to be careful with initialized_size extention in
+	  simultaneous file extensions.  This is given to us by holding i_sem
+	  on the inode.  The only places in the kernel when a file is resized
+	  are prepare/commit write and truncate for both of which i_sem is
+	  held.  Just have to be careful in readpage/writepage and all other
+	  helpers not running under i_sem that we play nice...
+	  Also need to be careful with initialized_size extention in
 	  ntfs_prepare_write. Basically, just be _very_ careful in this code...
-	  OTOH, perhaps i_sem, which is held accross generic_file_write is
-	  sufficient for synchronisation here. We then just need to make sure
-	  ntfs_readpage/writepage/truncate interoperate properly with us.
-	  UPDATE: The above is all ok as it is due to i_sem held.  The only
-	  thing that needs to be checked is ntfs_writepage() which does not
-	  hold i_sem.  It cannot change i_size but it needs to cope with a
-	  concurrent i_size change.
+	  UPDATE: The only things that need to be checked are read/writepage

-2.1.23-WIP
+2.1.23 - Implement extension of resident files and make writing safe as well as
+	 many bug fixes, cleanups, and enhancements...
 
 	- Add printk rate limiting for ntfs_warning() and ntfs_error() when
 	  compiled without debug.  This avoids a possible denial of service
 	  attack.  Thanks to Carl-Daniel Hailfinger from SuSE for pointing this
 	  out.
+	- Fix compilation warnings on ia64.  (Randy Dunlap)
+	- Use i_size_{read,write}() instead of reading i_size by hand and cache
+	  the value where apropriate.
+	- Add size_lock to the ntfs_inode structure.  This is an rw spinlock
+	  and it locks against access to the inode sizes.  Note, ->size_lock
+	  is also accessed from irq context so you must use the _irqsave and
+	  _irqrestore lock and unlock functions, respectively.  Protect all
+	  accesses to allocated_size, initialized_size, and compressed_size.
+	- Minor optimization to fs/ntfs/super.c::ntfs_statfs() and its helpers.
+	- Implement extension of resident files in the regular file write code
+	  paths (fs/ntfs/aops.c::ntfs_{prepare,commit}_write()).  At present
+	  this only works until the data attribute becomes too big for the mft
+	  record after which we abort the write returning -EOPNOTSUPP from
+	  ntfs_prepare_write().
+	- Add disable_sparse mount option together with a per volume sparse
+	  enable bit which is set appropriately and a per inode sparse disable
+	  bit which is preset on some system file inodes as appropriate.
+	- Enforce that sparse support is disabled on NTFS volumes pre 3.0.
+	- Fix a bug in fs/ntfs/runlist.c::ntfs_mapping_pairs_decompress() in
+	  the creation of the unmapped runlist element for the base attribute
+	  extent.
+	- Split ntfs_map_runlist() into ntfs_map_runlist() and a non-locking
+	  helper ntfs_map_runlist_nolock() which is used by ntfs_map_runlist().
+	  This allows us to map runlist fragments with the runlist lock already
+	  held without having to drop and reacquire it around the call.  Adapt
+	  all callers.
+	- Change ntfs_find_vcn() to ntfs_find_vcn_nolock() which takes a locked
+	  runlist.  This allows us to find runlist elements with the runlist
+	  lock already held without having to drop and reacquire it around the
+	  call.  Adapt all callers.
+	- Change time to u64 in time.h::ntfs2utc() as it otherwise generates a
+	  warning in the do_div() call on sparc32.  Thanks to Meelis Roos for
+	  the report and analysis of the warning.
+	- Fix a nasty runlist merge bug when merging two holes.
+	- Set the ntfs_inode->allocated_size to the real allocated size in the
+	  mft record for resident attributes (fs/ntfs/inode.c).
+	- Small readability cleanup to use "a" instead of "ctx->attr"
+	  everywhere (fs/ntfs/inode.c).
+	- Make fs/ntfs/namei.c::ntfs_get_{parent,dentry} static and move the
+	  definition of ntfs_export_ops from fs/ntfs/super.c to namei.c.  Also,
+	  declare ntfs_export_ops in fs/ntfs/ntfs.h.
+	- Correct sparse file handling.  The compressed values need to be
+	  checked and set in the ntfs inode as done for compressed files and
+	  the compressed size needs to be used for vfs inode->i_blocks instead
+	  of the allocated size, again, as done for compressed files.
+	- Add AT_EA in addition to AT_DATA to whitelist for being allowed to be
+	  non-resident in fs/ntfs/attrib.c::ntfs_attr_can_be_non_resident().
+	- Add fs/ntfs/attrib.c::ntfs_attr_vcn_to_lcn_nolock() used by the new
+	  write code.
+	- Fix bug in fs/ntfs/attrib.c::ntfs_find_vcn_nolock() where after
+	  dropping the read lock and taking the write lock we were not checking
+	  whether someone else did not already do the work we wanted to do.
+	- Rename fs/ntfs/attrib.c::ntfs_find_vcn_nolock() to
+	  ntfs_attr_find_vcn_nolock() and update all callers.
+	- Add fs/ntfs/attrib.[hc]::ntfs_attr_make_non_resident().
+	- Fix sign of various error return values to be negative in
+	  fs/ntfs/lcnalloc.c.
+	- Modify ->readpage and ->writepage (fs/ntfs/aops.c) so they detect and
+	  handle the case where an attribute is converted from resident to
+	  non-resident by a concurrent file write.
+	- Remove checks for NULL before calling kfree() since kfree() does the
+	  checking itself.  (Jesper Juhl)
+	- Some utilities modify the boot sector but do not update the checksum.
+	  Thus, relax the checking in fs/ntfs/super.c::is_boot_sector_ntfs() to
+	  only emit a warning when the checksum is incorrect rather than
+	  refusing the mount.  Thanks to Bernd Casimir for pointing this
+	  problem out.
+	- Update attribute definition handling.
+	- Add NTFS_MAX_CLUSTER_SIZE and NTFS_MAX_PAGES_PER_CLUSTER constants.
+	- Use NTFS_MAX_CLUSTER_SIZE in super.c instead of hard coding 0x10000.
+	- Use MAX_BUF_PER_PAGE instead of variable sized array allocation for
+	  better code generation and one less sparse warning in fs/ntfs/aops.c.
+	- Remove spurious void pointer casts from fs/ntfs/.  (Pekka Enberg)
+	- Use C99 style structure initialization after memory allocation where
+	  possible (fs/ntfs/{attrib.c,index.c,super.c}).  Thanks to Al Viro and
+	  Pekka Enberg.
+	- Stamp the transaction log ($UsnJrnl), aka user space journal, if it
+	  is active on the volume and we are mounting read-write or remounting
+	  from read-only to read-write.
+	- Fix a bug in address space operations error recovery code paths where
+	  if the runlist was not mapped at all and a mapping error occured we
+	  would leave the runlist locked on exit to the function so that the
+	  next access to the same file would try to take the lock and deadlock.
+	- Detect the case when Windows has been suspended to disk on the volume
+	  to be mounted and if this is the case do not allow (re)mounting
+	  read-write.  This is done by parsing hiberfil.sys if present.
+	- Fix several occurences of a bug where we would perform 'var & ~const'
+	  with a 64-bit variable and a int, i.e. 32-bit, constant.  This causes
+	  the higher order 32-bits of the 64-bit variable to be zeroed.  To fix
+	  this cast the 'const' to the same 64-bit type as 'var'.
+	- Change the runlist terminator of the newly allocated cluster(s) to
+	  LCN_ENOENT in ntfs_attr_make_non_resident().  Otherwise the runlist
+	  code gets confused.
+	- Add an extra parameter @last_vcn to ntfs_get_size_for_mapping_pairs()
+	  and ntfs_mapping_pairs_build() to allow the runlist encoding to be
+	  partial which is desirable when filling holes in sparse attributes.
+	  Update all callers.
+	- Change ntfs_map_runlist_nolock() to only decompress the mapping pairs
+	  if the requested vcn is inside it.  Otherwise we get into problems
+	  when we try to map an out of bounds vcn because we then try to map
+	  the already mapped runlist fragment which causes
+	  ntfs_mapping_pairs_decompress() to fail and return error.  Update
+	  ntfs_attr_find_vcn_nolock() accordingly.
+	- Fix a nasty deadlock that appeared in recent kernels.
+	  The situation: VFS inode X on a mounted ntfs volume is dirty.  For
+	  same inode X, the ntfs_inode is dirty and thus corresponding on-disk
+	  inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging
+	  to the table of inodes, i.e. $MFT, inode 0.
+	  What happens:
+	  Process 1: sys_sync()/umount()/whatever...  calls
+	  __sync_single_inode() for $MFT -> do_writepages() -> write_page for
+	  the dirty page containing the on-disk inode X, the page is now locked
+	  -> ntfs_write_mst_block() which clears PageUptodate() on the page to
+	  prevent anyone else getting hold of it whilst it does the write out.
+	  This is necessary as the on-disk inode needs "fixups" applied before
+	  the write to disk which are removed again after the write and
+	  PageUptodate is then set again.  It then analyses the page looking
+	  for dirty on-disk inodes and when it finds one it calls
+	  ntfs_may_write_mft_record() to see if it is safe to write this
+	  on-disk inode.  This then calls ilookup5() to check if the
+	  corresponding VFS inode is in icache().  This in turn calls ifind()
+	  which waits on the inode lock via wait_on_inode whilst holding the
+	  global inode_lock.
+	  Process 2: pdflush results in a call to __sync_single_inode for the
+	  same VFS inode X on the ntfs volume.  This locks the inode (I_LOCK)
+	  then calls write-inode -> ntfs_write_inode -> map_mft_record() ->
+	  read_cache_page() for the page (in page cache of table of inodes
+	  $MFT, inode 0) containing the on-disk inode.  This page has
+	  PageUptodate() clear because of Process 1 (see above) so
+	  read_cache_page() blocks when it tries to take the page lock for the
+	  page so it can call ntfs_read_page().
+	  Thus Process 1 is holding the page lock on the page containing the
+	  on-disk inode X and it is waiting on the inode X to be unlocked in
+	  ifind() so it can write the page out and then unlock the page.
+	  And Process 2 is holding the inode lock on inode X and is waiting for
+	  the page to be unlocked so it can call ntfs_readpage() or discover
+	  that Process 1 set PageUptodate() again and use the page.
+	  Thus we have a deadlock due to ifind() waiting on the inode lock.
+	  The solution: The fix is to use the newly introduced
+	  ilookup5_nowait() which does not wait on the inode's lock and hence
+	  avoids the deadlock.  This is safe as we do not care about the VFS
+	  inode and only use the fact that it is in the VFS inode cache and the
+	  fact that the vfs and ntfs inodes are one struct in memory to find
+	  the ntfs inode in memory if present.  Also, the ntfs inode has its
+	  own locking so it does not matter if the vfs inode is locked.
