[Cluster-devel] [PATCH 01/12] GFS2: Alter arguments of gfs2_quota/statfs_sync



These two functions are altered so that gfs2_quota_sync may
in future be called directly from the VFS. The GFS2 superblock
changes to a VFS super block and there is an addition of an int
argument which is currently ignored.
