+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.
