Merge tag 'nfs-for-4.8-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs 

Pull NFS client bugfixes from Trond Myklebust:
 "Highlights include:

   - Stable patch from Olga to fix RPCSEC_GSS upcalls when the same user
     needs multiple different security services (e.g.  krb5i and krb5p).

   - Stable patch to fix a regression introduced by the use of
     SO_REUSEPORT, and that prevented the use of multiple different NFS
     versions to the same server.

   - TCP socket reconnection timer fixes.

   - Patch from Neil to disable the use of IPv6 temporary addresses"

* tag 'nfs-for-4.8-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
