Retested v2 on a Colibri VF50 (7.2-rc1, ACM next to NCM) with a 3 s delay in gs_close(): freeing the line during a close, opens of the retired line, re-creating it and 4 add/remove cycles with the port held open behave as with v1, every port is destroyed once and there are no new kernel warnings. 3000 opens racing 30 creations of the function all succeeded.
