Merge tag 'nfs-for-3.4-3' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client bugfixes from Trond Myklebust:
 - Fix NFSv4 infinite loops on open(O_TRUNC)
 - Fix an Oops and an infinite loop in the NFSv4 flock code
 - Don't register the PipeFS filesystem until it has been set up
 - Fix an Oops in nfs_try_to_update_request
 - Don't reuse NFSv4 open owners: fixes a bad sequence id storm.

* tag 'nfs-for-3.4-3' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
  NFSv4: Keep dropped state owners on the LRU list for a while
  NFSv4: Ensure that we don't drop a state owner more than once
  NFSv4: Ensure we do not reuse open owner names
  nfs: Enclose hostname in brackets when needed in nfs_do_root_mount
  NFS: put open context on error in nfs_flush_multi
  NFS: put open context on error in nfs_pagein_multi
  NFSv4: Fix open(O_TRUNC) and ftruncate() error handling
  NFSv4: Ensure that we check lock exclusive/shared type against open modes
  NFSv4: Ensure that the LOCK code sets exception->inode
  NFS: check for req==NULL in nfs_try_to_update_request cleanup
  SUNRPC: register PipeFS file system after pernet sybsystem
