That's a problem unfortunately. We can't really propose an API,
because we don't know enough about SMB semantics. And we can't propose
anythying to the kernel, as it needs to be perfect from day 1. We need
to play with this in user space before we can approach you guys, so
this means we need cooperation by Ganesha. The kernel is very hostile
to anything that comes from the SMB world (see richacls), so we need a
100% water-proof story with two external users before approaching you
with a proposal.
