    nfs: Add some support for POSIX draft ACLs
    
    An internet draft (expected to become an RFC someday)
    https://datatracker.ietf.org/doc/draft-ietf-nfsv4-posix-acls
    describes an extension to NFSv4.2 to handle POSIX draft ACLs.
    
    This is the final patch in the series that enables
    the extension of NFSv4.2 to support POSIX draft ACLs.
    At this time, only UFS mounted with the "acls" option
    will work, and only for FreeBSD built with these patches.
    Patches for client and server for the Linux kernel are
    in the works.  (I'll admit my next little project is
    cleaning the Linux patches up for submission for upstream.)
    
    To make these changes really useful, the FreeBSD port
    of OpenZFS needs to be patched to add POSIX draft ACL
    support.  (Support for POSIX draft ACLs is already in
    the Linux port of OpenZFS.)
    
    Interopeability with NFSv4.2 clients and servers that
    do not support this extension should not be a problem.
    
    Fixes:  a35bbd5d9f5f ("nfscommon: Add some support for POSIX draft ACLs")
