I have read mailing list discussion http://marc.info/?l=linux-nfs&m=138245168524204&w=2 from the earlier attempt that Andy did in 2013. Suggestion was to propose a system call interface to provide such functionality which I did. I haven't had luck with VFS accepting functionality so I'm pre-emptively asking about an alternative approach that NFS could use. There is the original proposal to use a keyring, then there is pipe_fs or I don't know maybe sysctl? Does one sound better than the other in your opinion? Thank you.
