 	- Fix various bugs in the runlist merging code.  (Based on libntfs
 	  changes by Richard Russon.)
+	- Fix sparse warnings that have crept in over time.
+	- Change ntfs_cluster_free() to require a write locked runlist on entry

+	  runlist is passed in. In the process also change it to take an ntfs

+	  all over the system's ram.
 
 2.1.23 - Implement extension of resident files and make writing safe as well as
