GFS2: merge window

Browse Source 
Here is a list of patches we've accumulated for GFS2 for the current upstream
 merge window. This time we've only got six patches, many of which are very small:
 
 - Three cleanups from Andreas Gruenbacher, including a nice cleanup of
   the sequence file code for the sbstats debugfs file.
 - A patch from Ben Hutchings that changes statistics variables from signed
   to unsigned.
 - Two patches from me that increase GFS2's glock scalability by switching
   from a conventional hash table to rhashtable.
