A fair point here. Perhaps calling them 'legacy' is a bit harsh, as
these are still useful for short-term v4.1 iSCSI target debugging
purposes. In the long run these do need to be converted to use debugfs
(along with the rest of drivers/target/ as well), but this is currently
a lower priority item on the TODO for the initial merge.
