Reverted the linux-next commit ee8ad8190cb1 (“vfs, fsinfo: Add an RCU safe per-ns mount list”) fixed the null-ptr-deref.    

Okay, I'm dropping this commit for now.    

What's the point of re-adding this buggy patch to linux-next again since
0621 without fixing the previous reported issue at all? Reverting the
commit will still fix the crash below immediately, i.e.,

dbc87e74d022 ("vfs, fsinfo: Add an RCU safe per-ns mount list")  

I have added a revert of that commit to linux-next today.

I am still reverting that commit ...
