         - Enable the code for setting the NT4 compatibility flag when we start
           making NTFS 1.2 specific modifications.
 
+2.1.24 - Lots of bug fixes and support more clean journal states.
+
+        - 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.
+        - Modify fs/ntfs/malloc.h::ntfs_malloc_nofs() to do the kmalloc() based
+          allocations with __GFP_HIGHMEM, analogous to how the vmalloc() based
+          allocations are done.
+        - Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to
+          ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and
+          hence cannot fail.
+        - Use ntfs_malloc_nofs_nofail() in the two critical regions in
+          fs/ntfs/runlist.c::ntfs_runlists_merge().  This means we no longer
+          need to panic() if the allocation fails as it now cannot fail.
+        - Fix two nasty runlist merging bugs that had gone unnoticed so far.
+          Thanks to Stefano Picerno for the bug report.
+        - Remove two bogus BUG_ON()s from fs/ntfs/mft.c.
+        - Fix handling of valid but empty mapping pairs array in
+          fs/ntfs/runlist.c::ntfs_mapping_pairs_decompress().
+        - Report unrepresentable inodes during ntfs_readdir() as KERN_WARNING
+          messages and include the inode number.  Thanks to Yura Pakhuchiy for
+          pointing this out.
+        - Change ntfs_rl_truncate_nolock() to throw away the runlist if the new
+          length is zero.
+        - Add runlist.[hc]::ntfs_rl_punch_nolock() which punches a caller
+          specified hole into a runlist.
+        - Fix a bug in fs/ntfs/index.c::ntfs_index_lookup().  When the returned
+          index entry is in the index root, we forgot to set the @ir pointer in
+          the index context.  Thanks to Yura Pakhuchiy for finding this bug.
+        - Remove bogus setting of PageError in ntfs_read_compressed_block().
+        - Add fs/ntfs/attrib.[hc]::ntfs_resident_attr_value_resize().
+        - Fix a bug in ntfs_map_runlist_nolock() where we forgot to protect
+          access to the allocated size in the ntfs inode with the size lock.
+        - Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to
+          return LCN_ENOENT when there is no runlist and the allocated size is
+          zero.
+        - Fix load_attribute_list() to handle the case of a NULL runlist.
+        - Fix handling of sparse attributes in ntfs_attr_make_non_resident().
+        - Add BUG() checks to ntfs_attr_make_non_resident() and ntfs_attr_set()
+          to ensure that these functions are never called for compressed or
+          encrypted attributes.
+        - Fix cluster (de)allocators to work when the runlist is NULL and more
+          importantly to take a locked runlist rather than them locking it
+          which leads to lock reversal.
+        - Truncate {a,c,m}time to the ntfs supported time granularity when
+          updating the times in the inode in ntfs_setattr().
+        - Fixup handling of sparse, compressed, and encrypted attributes in
+          fs/ntfs/inode.c::ntfs_read_locked_{,attr_,index_}inode(),
+          fs/ntfs/aops.c::ntfs_{read,write}page().
+        - Make ntfs_write_block() not instantiate sparse blocks if they contain
+          only zeroes.
+        - Optimize fs/ntfs/aops.c::ntfs_write_block() by extending the page
+          lock protection over the buffer submission for i/o which allows the
+          removal of the get_bh()/put_bh() pairs for each buffer.
+        - Fix fs/ntfs/aops.c::ntfs_{read,write}_block() to handle the case
+          where a concurrent truncate has truncated the runlist under our feet.
+        - Fix page_has_buffers()/page_buffers() handling in fs/ntfs/aops.c.
+        - In fs/ntfs/aops.c::ntfs_end_buffer_async_read(), use a bit spin lock
+          in the first buffer head instead of a driver global spin lock to
+          improve scalability.
+        - Minor fix to error handling and error message display in
+          fs/ntfs/aops.c::ntfs_prepare_nonresident_write(). 
+
 2.1.23 - Implement extension of resident files and make writing safe as well as
          many bug fixes, cleanups, and enhancements...
