 Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
 
+2.1.26:
+        - Implement support for sector sizes above 512 bytes (up to the maximum
+          supported by NTFS which is 4096 bytes).
+        - Enhance support for NTFS volumes which were supported by Windows but
+          not by Linux due to invalid attribute list attribute flags.
+        - A few minor updates and bug fixes.
 2.1.25:
         - Write support is now extended with write(2) being able to both
           overwrite existing file data and to extend files.  Also, if a write

 largest node numbers in the range.  For example, mpol=bind:0-3,5,7,9-15
 
+Note that trying to mount a tmpfs with an mpol option will fail if the
+running kernel does not support NUMA; and will fail if its nodelist
+specifies a node >= MAX_NUMNODES.  If your system relies on that tmpfs
+being mounted, but from time to time runs a kernel built without NUMA
+capability (perhaps a safe recovery kernel), or configured to support
+fewer nodes, then it is advisable to omit the mpol option from automatic
+mount options.  It can be added later, when the tmpfs is already mounted
+on MountPoint, by 'mount -o remount,mpol=Policy:NodeList MountPoint'.

 To specify the initial root directory you can use the following mount
