[Trond Myklebust <trondmy@hammerspace.com>]

Hi Linus,

The following changes since commit 009c9aa5be652675a06d5211e1640e02bbb1c33d:

  Linux 5.13-rc6 (2021-06-13 14:43:10 -0700)

are available in the Git repository at:

  git://git.linux-nfs.org/projects/trondmy/linux-nfs.git tags/nfs-for-5.14-1

for you to fetch changes up to 878b3dfc42c4ddbf9e38cd9061e3ddd99a69747a:

  Merge part 2 of branch 'sysfs-devel' (2021-07-08 14:03:26 -0400)

Please note that this branch was rebased today. The reason was I discovered
that one of the topic branches that was merged contained some duplicated patches
from the main branch (mea culpa). So the rebase simply removed those duplicates
from the topic branch.

Thanks
   Trond

NFS client updates for Linux 5.14

Highlights include:

Stable fixes:
- Two sunrpc fixes for deadlocks involving privileged rpc_wait_queues

Bugfixes
- SUNRPC: Avoid a KASAN slab-out-of-bounds bug in xdr_set_page_base()
- SUNRPC: prevent port reuse on transports which don't request it.
- NFSv3: Fix memory leak in posix_acl_create()
- NFS: Various fixes to attribute revalidation timeouts
- NFSv4: Fix handling of non-atomic change attribute updates
- NFSv4: If a server is down, don't cause mounts to other servers to
  hang as well
- pNFS: Fix an Oops in pnfs_mark_request_commit() when doing O_DIRECT
- NFS: Fix mount failures due to incorrect setting of the has_sec_mnt_opts
  filesystem flag
 - NFS: Ensure nfs_readpage returns promptly when an internal error occurs
 - NFS: Fix fscache read from NFS after cache error
 - pNFS: Various bugfixes around the LAYOUTGET operation

Features
- Multiple patches to add support for fcntl() leases over NFSv4.
- A sysfs interface to display more information about the various
  transport connections used by the RPC client
- A sysfs interface to allow a suitably privileged user to offline a
  transport that may no longer point to a valid server
- A sysfs interface to allow a suitably privileged user to change the
  server IP address used by the RPC client
