What does UCM_EVENT_STATUS_NEXT mean?

ucx (master)]$ git grep UCM_EVENT_STATUS_NEXT
src/ucm/api/ucm.h:     * It can return only UCM_EVENT_STATUS_NEXT

  174     /*
  175      * UCM_EVENT_VM_MAPPED, UCM_EVENT_VM_UNMAPPED

  177      * This is a "read-only" event which is called whenever memory is mapped
  178      * or unmapped from process address space, in addition to the other events.
  179      * It can return only UCM_EVENT_STATUS_NEXT.
  180      *

This description is outdated, since ucm_event_callback_t does not return a value
