Hi Linus,

The following changes since commit
63e2fffa59a9dd91e443b08832656399fd80b7f0:

  pNFS/flexfiles: Fix array overflow when flexfiles mirroring is
enabled (2020-11-30 10:52:22 -0500)

are available in the Git repository at:

  NFS/pNFS: Fix a typo in ff_layout_resend_pnfs_read() (2020-12-16
17:25:24 -0500)


Stephen Rothwell has noted that there are conflicts with the upstream
tree.
They are due to the last-minute fix to the NFSv4.2 READ_PLUS code in
5.10,
and due to the changes for the nfsd XDR code. The fixups should be
trivial
but please let me know if you'd prefer that I do so.

Cheers
  Trond

----------------------------------------------------------------
NFS client updates for Linux 5.11

Highlights include:

Features:
- NFSv3: Add emulation of lookupp() to improve open_by_filehandle()
  support.
- A series of patches to improve readdir performance, particularly with
  large directories.
- Basic support for using NFS/RDMA with the pNFS files and flexfiles
  drivers.
- Micro-optimisations for RDMA.
- RDMA tracing improvements.

Bugfixes:
- Fix a long standing bug with xs_read_xdr_buf() when receiving partial
  pages (Dan Aloni).
- Various fixes for getxattr and listxattr, when used over non-TCP
  transports.
- Fixes for containerised NFS from Sargun Dhillon.
- switch nfsiod to be an UNBOUND workqueue (Neil Brown).
- READDIR should not ask for security label information if there is no
  LSM policy. (Olga Kornievskaia)
- Avoid using interval-based rebinding with TCP in lockd (Calum
Mackay).
- A series of RPC and NFS layer fixes to support the NFSv4.2 READ_PLUS
code.
- A couple of fixes for pnfs/flexfiles read failover

Cleanups:
- Various cleanups for the SUNRPC xdr code in conjunction with the
  READ_PLUS fixes.

pr-tracker-bot doesn't seem to have reacted to this email.

I suspect it's because of the odd and unfortunate line breaks in it,
but who knows. Maybe it's just delayed (but the other filesystem pulls
seem to have been tracked).

Anyway, it's pulled, even if the automation seems to not have noticed.

Thanks! Much appreciated.
