Add the lseek SEEK_DATA/SEEK_HOLE support into xfs_io.
The result from the lseek() call will be printed to the output.
For example:

xfs_io>  lseek -h 609k
Type	Offset
hole	630784

v1 ->  v2 Add "-a" and "-r" options.
	 Simplify the output.
v2 ->  v3 Refactor for configure.in ->  configure.ac change.
	 SEEK_DATA with -1 offset behaves badly on older Linux.
	 Display error message as "ERR<errno>".
....
+
+#include<linux/fs.h>

I missed this first time around - why is this include necessary?

Take it out and you will find that it contains the
defines for SEEK_DATA/SEEK_HOLE.

--Mark.
