[GIT PULL] Please pull NFS client changes

[Trond Myklebust <trondmy@hammerspace.com>]

Hi Linus,

Apologies for the relatively high volume this late in -rc. This is mainly
fallout from the updates to the SUNRPC code that is being triggered from
less common combinations of NFS mount options.

Cheers
  Trond

  SUNRPC: Don't force a redundant disconnection in xs_read_stream() (2018-12-05 07:11:12 -0500)

----------------------------------------------------------------
NFS client bugfixes for Linux 4.20

Highlights include:

Stable fixes:
 - Fix a page leak when using RPCSEC_GSS/krb5p to encrypt data.

Bugfixes:
 - Fix a regression that causes the RPC receive code to hang
 - Fix call_connect_status() so that it handles tasks that got transmitted
   while queued waiting for the socket lock.
 - Fix a memory leak in call_encode()
 - Fix several other connect races.
 - Fix receive code error handling.
 - Use the discard iterator rather than MSG_TRUNC for compatibility with
   AF_UNIX/AF_LOCAL sockets.
 - nfs: don't dirty kernel pages read by direct-io
 - pnfs/Flexfiles fix to enforce per-mirror stateid only for NFSv4 data
   servers
