My mistake.  At that time, I noticed that there has comments about this
in xfs_ioc_bulkstat(), i.e,

 /* done = 1 if there are more stats to get and if bulkstat */
 /* should be called again (unused here, but used in dmapi) */

However, I failed to find out why it would be called by going through
the dmapi source code...

I'll keep this argument in next round of post.

Thanks,
