[illumos-Developer] webrev for 1107

[Gordon Ross]

I've seen this before, and I'm happy with most of it...

But one question now comes to mind:  This code is shared with
the nfsd listener (etc.) so I wonder, how did it work with the check;
  if (retnconf->nc_semantics == NC_TPI_CLTS) ... ?
Seems like that should have broken NFS[3,4] over TCP.
Would be good to understand why that was there.

BTW, it's used by the in-kernel part of the lock manager to
communicate with the user-space NFS status monitor.
(This code pre-dates doors, door up-calls, etc.)  We could
change it use a different mechanism, but we'd prefer to
minimize the scope of this work as much as possible.
(At least for now.)
