Can you also push this into the main CLI interface similar to how
all the other open flags can be specified? i.e.

$ xfs_io -d -c "pwrite 0 4k" foo

will open "foo" with O_DIRECT. Be nice just to be able to do

$ xfs_io -dT -c "pwrite 0 4k" foo/

to be able to test O_TMPFILE functionality

FWIW, any plans to add a "link" command to be able to link the
tmpfile into the namespace once it is created?

Cheers,

Dave.
