NAK on this whole thing. Linux does not support NFSv4 ACLs for pretty
good reasons. If you want to add it you'd have to do it properly (even
if that is a bad idea in my opinion). But adding a weird special case
for passthrough is a no-go. To be honest I really don't understand why
your (as in Hammerspae, not you personally) want to abuse the kernel
nfsd and nfs client for that. If you want to pass in the protocol do
it in userspace without burdening the kernel with it.
