This actually doesn't work for me on an old kernel, if that matters; it
fails with:

/mnt/test: Is a directory

and nothing catches that.  Old xfsprogs tries to open the file
in question RDWR even before it gets to the -T option (which
would fail, I guess), and you can't do that for directories.

So I suppose we could explicitly test for that when checking
flink:

        [ $command = "flink" ] && echo $testio | grep -q "Is a directory" && \
                _notrun "xfs_io flink support is missing"

or alternately, first just run xfs_io w/ the command but no file;
today, at least, that works:

[root@bp-05 xfstests]# xfs_io -c flink
command "flink" not found
[root@bp-05 xfstests]# xfs_io -c pread
[root@bp-05 xfstests]# 

so could do this before the case statement:

        $XFS_IO_PROG -c $command 2>&1 | grep -q "not found" && \
                _notrun "xfs_io $command support is missing"

but that might be subject to future changes in xfs_io command
parsing...
