Roman, the issue is a moot.
Basically lsof tries to figure out the path corresponding to a file descriptor which represents sys V shared memory segment.
The kernel complains about the root dentry of shmfs (an in-kernel tmpfs which implements sys V shared memory,
this tmpfs is not exposed to the userspace directly) having no expected d_name.
The warning is harmless and can be ignored.
