Just because it's reproducible doesn't mean it's a bug.
lsof/netstat inspects the file descriptors (found under /proc/$pid/fd) and tries to figure out
the path corresponding to each of them. However some of the file descriptors belong to
the internal kernel filesystems/mounts (for instance, shmfs, anonpipefs, also file descriptors
created by eventfd(), epoll_create(), inotify_init(), etc). The kernel complains about the root
dentry of the corresponding (pseudo)filesystem having no proper d_name.
The warning is harmless and can be ignored.
