  FreeBSD src repository

  Modified files:
    sys/sys              vnode.h 
    sys/kern             vfs_subr.c 
    sys/ufs/ffs          ffs_extern.h ffs_vfsops.c fs.h 
    sys/ufs/ufs          ufs_inode.c ufs_vnops.c 
  Added files:
    sys/ufs/ufs          gjournal.h ufs_gjournal.c 
  Log:
  Add gjournal specific code to the UFS file system:
  - Add FS_GJOURNAL flag which enables gjournal support on a file system.
  - Add cg_unrefs field to the cylinder group structure which holds
    number of unreferenced (orphaned) inodes in the given cylinder group.
  - Add fs_unrefs field to the super block structure which holds
    total number of unreferenced (orphaned) inodes.
  - When file or a directory is orphaned (last reference is removed, but
    object is still open), increase fs_unrefs and cg_unrefs fields,
    which is a hint for fsck in which cylinder groups looks for such
    (orphaned) objects.
  - When file is last closed, decrease {fs,cg}_unrefs fields.
  - Add VV_DELETED vnode flag which points at orphaned objects.
