We got a bunch of:

[    0.457561][    T0] ref_tracker: ref_tracker: unable to create debugfs file for net_refcnt@ffffffff92da4870: -ENOENT
[    0.457561][    T0] ref_tracker: ref_tracker: unable to create debugfs file for net_notrefcnt@ffffffff92da48f8: -ENOENT

[    0.973191][    T1] ref_tracker: ref_tracker: unable to create debugfs file for netdev@ffff888004d0c5a8: -ENOENT

[    1.150784][    T1] ref_tracker: ref_tracker: unable to create debugfs file for netdev@ffff8880053fc5a8: -ENOENT

[    1.660680][    T1] ref_tracker: ref_tracker: unable to create debugfs file for netdev@ffff8880085f95a8: -ENOENT

in the CI at boot. Presumably init_net and loopback.
