Hi Tom - if you look at the xfs superblock in kdb, you'll see:

[0]kdb> xsb 0xc6140824
...
rootino 128 rbmino 129 rsumino 130
...

and these are:

  xfs_ino_t       sb_rbmino;      /* bitmap inode for realtime extents */
  xfs_ino_t       sb_rsumino;     /* summary inode for rt bitmap */

However, I'm not sure offhand why these show up even if CONFIG_XFS_RT
is not enabled.

-Eric
