@@ -22,7 +22,7 @@ ToDo/Notes:
        - Enable the code for setting the NT4 compatibility flag when we start
          making NTFS 1.2 specific modifications.
 
-2.1.24-WIP
+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.
@@ -34,6 +34,66 @@ ToDo/Notes:
          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.
+       - 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().
+       - Change the mount options {u,f,d}mask to always parse the number as
+         an octal number to conform to how chmod(1) works, too.  Thanks to
+         Giuseppe Bilotta and Horst von Brand for pointing out the errors of
+         my ways.
+       - Fix various bugs in the runlist merging code.  (Based on libntfs
+         changes by Richard Russon.)
 
 2.1.23 - Implement extension of resident files and make writing safe as well as
         many bug fixes, cleanups, and enhancements...
