Sorry, I was wrong about this. It would break the subsequent
$XFS_IO_PROG -c "help $command" | grep ... command if another $param is
specified. Seems adding $param to falloc command is the right way, as
what Darrick did to fiemap in his new test.

-               testio=`$XFS_IO_PROG -F -f -c "falloc 0 1m" $testfile 2>&1`
+               testio=`$XFS_IO_PROG -F -f -c "falloc $param 0 1m" $testfile 2>&1`

Do you mind me updating these three patches accordingly? Or can you send
out new version if you like?

Thanks! And sorry again!

Eryu

P.S. I'm thinking of converting all the case switches (except the
default one) in _require_xfs_io_command() to actually run the $command
with $param, and doing other cleanups, but that won't block this patch
and I can do it in another patch.
