    lockd: Start PF_INET6 listener only if IPv6 support is available · eb16e907
    Chuck Lever authored
    Apparently a lot of people need to disable IPv6 completely on their
    distributor-built systems, which have CONFIG_IPV6_MODULE enabled at
    build time.
    
    They do this by blacklisting the ipv6.ko module.  This causes the
    creation of the lockd service listener to fail if CONFIG_IPV6_MODULE
    is set, but the module cannot be loaded.
    
    Now that the kernel's PF_INET6 RPC listeners are completely separate
    from PF_INET listeners, we can always start PF_INET.  Then lockd can
    try to start PF_INET6, but it isn't required to be available.
    
    Note this has the added benefit that NLM callbacks from AF_INET6
    servers will never come from AF_INET remotes.  We no longer have to
    worry about matching mapped IPv4 addresses to AF_INET when comparing
    addresses.
