Comment 6 for bug 1758242

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_unplug
0000000000000000 t trace_event_define_fields_block_split
0000000000000000 t trace_event_define_fields_block_bio_remap
0000000000000000 t trace_event_define_fields_block_rq_remap
0000000000000000 T blk_dev_init
0000000000000000 t blk_settings_init
0000000000000000 t blk_ioc_init
0000000000000000 t blk_softirq_init
0000000000000000 t blk_mq_init
0000000000000000 t genhd_device_init
0000000000000000 t proc_genhd_init

4.15:
          (null) t btrfs_space_info_show_total_bytes_pinned [btrfs]
          (null) t space_info_release [btrfs]
          (null) t btrfs_release_fsid_kobj [btrfs]
          (null) t quota_override_store [btrfs]
          (null) t btrfs_label_store [btrfs]
          (null) t btrfs_feature_attr_store [btrfs]
          (null) t addrm_unknown_feature_attrs [btrfs]
          (null) b btrfs_feature_attrs [btrfs]
          (null) r supported_feature_masks [btrfs]
          (null) t __btrfs_sysfs_remove_fsid [btrfs]
          (null) t can_modify_feature.isra.4 [btrfs]
          (null) t btrfs_feature_attr_show [btrfs]
          (null) t btrfs_feature_visible [btrfs]

I think the test may need to be updated.
