Subject[GIT PULL] Please pull NFS client changes
Date
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
