Question about inode security blob

I'm trying to learn the security blob infrastructure for my future LSM
Unlike other blobs, I found inode security blob has a special pattern. I
couldn’t find useful information on the web so I think this mail list is
the most appropriate place to ask this question.
The BPF and SELinux will check whether the inode->i_security is NULL
But for smack, it doesn't do such a check
Is this because smack_set_mnt_opts() already does the NULL check at
Also, I wonder in which situation will the inode->i_security be NULL?
Thanks, and I hope I could make my contributions to LSM soon.
