CVE-2011-2689 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-2689):
  The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before
  3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of
  the block size, which allows local users to cause a denial of service (BUG
  and system crash) by arranging for all resource groups to have too little
  free space.
