-       - Enable the code for setting the NT4 compatibility flag when we start
-         making NTFS 1.2 specific modifications.
+
+2.1.29 - Fix a deadlock at mount time.
+
+       - During mount the VFS holds s_umount lock on the superblock.  So when
+         we try to empty the journal $LogFile contents by calling
+         ntfs_attr_set() when the machine does not have much memory and the
+         journal is large ntfs_attr_set() results in the VM trying to balance
+         dirty pages which in turn tries to that the s_umount lock and thus we
+         get a deadlock.  The solution is to not use ntfs_attr_set() and
+         instead do the zeroing by hand at the block level rather than page
+         cache level.
+       - Fix sparse warnings.
+
+2.1.28 - Fix a deadlock.
+
+       - Fix deadlock in fs/ntfs/inode.c::ntfs_put_inode().  Thanks to Sergey
+         Vlasov for the report and detailed analysis of the deadlock.  The fix
+         involved getting rid of ntfs_put_inode() altogether and hence NTFS no
+         longer has a ->put_inode super operation.
+
+2.1.27 - Various bug fixes and cleanups.
+
+       - Fix two compiler warnings on Alpha.  Thanks to Andrew Morton for
+         reporting them.
+       - Fix an (innocent) off-by-one error in the runlist code.
+       - Fix a buggette in an "should be impossible" case handling where we
+         continued the attribute lookup loop instead of aborting it.
+       - Use buffer_migrate_page() for the ->migratepage function of all ntfs
+         address space operations.
+       - Fix comparison of $MFT and $MFTMirr to not bail out when there are
+         unused, invalid mft records which are the same in both $MFT and
+         $MFTMirr.
+       - Add support for sparse files which have a compression unit of 0.
+       - Remove all the make_bad_inode() calls.  This should only be called
+         from read inode and new inode code paths.
+       - Limit name length in fs/ntfs/unistr.c::ntfs_nlstoucs() to maximum
+         allowed by NTFS, i.e. 255 Unicode characters, not including the
+         terminating NULL (which is not stored on disk).
+       - Improve comments on file attribute flags in fs/ntfs/layout.h.
+       - Fix a bug in fs/ntfs/inode.c::ntfs_read_locked_index_inode() where we
+         forgot to update a temporary variable so loading index inodes which
+         have an index allocation attribute failed.
+       - Add a missing call to flush_dcache_mft_record_page() in
+         fs/ntfs/inode.c::ntfs_write_inode().
+       - Handle the recently introduced -ENAMETOOLONG return value from
+         fs/ntfs/unistr.c::ntfs_nlstoucs() in fs/ntfs/namei.c::ntfs_lookup().
+       - Semaphore to mutex conversion.  (Ingo Molnar)
+
+2.1.26 - Minor bug fixes and updates.
+
+       - Fix a potential overflow in file.c where a cast to s64 was missing in
+         a left shift of a page index.
+       - The struct inode has had its i_sem semaphore changed to a mutex named
+         i_mutex.
+       - We have struct kmem_cache now so use it instead of the typedef
+         kmem_cache_t.  (Pekka Enberg)
+       - Implement support for sector sizes above 512 bytes (up to the maximum
+         supported by NTFS which is 4096 bytes).
+       - Do more detailed reporting of why we cannot mount read-write by
+         special casing the VOLUME_MODIFIED_BY_CHKDSK flag.
+       - Miscellaneous updates to layout.h.
+       - Cope with attribute list attribute having invalid flags.  Windows
+         copes with this and even chkdsk does not detect or fix this so we
+         have to cope with it, too.  Thanks to Pawel Kot for reporting the
+         problem.
