Why is the operation useful?  Isn't the debug key sufficient?

# xl debug-key g
(XEN) gnttab_usage_print_all [ key 'g' pressed
(XEN)       -------- active --------       -------- shared --------
(XEN) [ref] localdom mfn      pin          localdom gmfn     flags
(XEN) grant-table for remote domain:    0 ... no active grant table entries
(XEN) gnttab_usage_print_all ] done
