Which is ok. since 'missed_bridges' is static and allocated memory will eventually be freed when ovn-controller exits. But will valgrind complain about the memory leak ? Is it worth making this file scope and adding patch_init(), patch_destroy() functions which will init the sset and destroy it. Any thoughts ?
