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.
