Our FSAL does not support NFS4.1 yet and I'd like to refuse to mount for 4.1 version. I'm exploring 2 following options:

1/ A way to tell ganesha that we don't have export for 4.1 at init

2/ Return NOTSUPPORTED for one of the NFS message during mount stage (like PUTFH, GETATTR, etc). But related function in the fsal level do not have input param containing the minorversion.

Can anyone give me a hint?

Thank you
