Your changes to mem_event_disable() already contain the changes I would
have made as well, making changes only with the ring lock held.
Minor detail:
In mem_event_enable(), the call to mem_event_ring_lock_init() should be
moved up before the pointers are assigned to close the tiny window
between lock init and assignment.
