This failure appears to be happening because of a change in syntax in
/proc/kallsyms between 4.13 and 4.15 for non-root users:
4.13:
0000000000000000 t trace_event_define_fields_block_bio_queue
0000000000000000 t trace_event_define_fields_block_get_rq

0000000000000000 t trace_event_define_fields_block_rq_remap

0000000000000000 t genhd_device_init
0000000000000000 t proc_genhd_init
4.15:

I think the test may need to be updated.
