Log: xen: check if there are clients waiting in gnttab_end_foreign_access_references Without a call to check_free_callbacks() clients waiting for grant references would not be woken up even when there are sufficient grant references available. The check was likely left out as a mistake when the function was first added. Note that other functions used to free grant references already call check_free_callbacks.
