Can I suggest that you read the man page and understand how the
command is supposed to work before posting patches to change the
test? i.e the -T option /requires/ a directory to be supplied to it:

    -T  create a temporary file not linked into the filesystem
	namespace (O_TMPFILE).  The pathname passed must refer to a
	directory which is  treated as virtual parent for the newly
	created invisible file.  Can not be used together with the
	-r option.

IOWs, there is nothing wrong with the test code - if you if
you are getting an EISDIR error here then something is broken with
the xfs_io binary you are using.

And, because I haven't merged fsmap support into xfs_io yet, it's
very likely there is a problem in the prototype patchset you are
running. Perhaps that's worth reporting to the patchset author....

Cheers,

Dave.
