Pull gfs2 fixes from Steven Whitehouse:
 "Here are a number of small fixes for GFS2.

  There is a fix for FIEMAP on large sparse files, a negative dentry
  hashing fix, a fix for flock, and a bug fix relating to d_splice_alias
  usage.

  There are also (patches 1 and 5) a couple of updates which are less
  critical, but small and low risk"
