Pull NFS client updates from Trond Myklebust:
 "Highlights include:

  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

  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"
