         - 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().
 
 2.1.23 - Implement extension of resident files and make writing safe as well as
          many bug fixes, cleanups, and enhancements...
