Merge branch 'bugfixes' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6

* 'bugfixes' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6:
  nfs: don't lose MS_SYNCHRONOUS on remount of noac mount
  NFS: Return meaningful status from decode_secinfo()
  NFSv4: Ensure we request the ordinary fileid when doing readdirplus
  NFSv4: Ensure that clientid and session establishment can time out
  SUNRPC: Allow RPC calls to return ETIMEDOUT instead of EIO
  NFSv4.1: Don't loop forever in nfs4_proc_create_session
  NFSv4: Handle NFS4ERR_WRONGSEC outside of nfs4_handle_exception()
  NFSv4.1: Don't update sequence number if rpc_task is not sent
  NFSv4.1: Ensure state manager thread dies on last umount
  SUNRPC: Fix the SUNRPC Kerberos V RPCSEC_GSS module dependencies
  NFS: Use correct variable for page bounds checking
  NFS: don't negotiate when user specifies sec flavor
  NFS: Attempt mount with default sec flavor first
  NFS: flav_array honors NFS_MAX_SECFLAVORS
  NFS: Fix infinite loop in gss_create_upcall()
  Don't mark_inode_dirty_sync() while holding lock
  NFS: Get rid of pointless test in nfs_commit_done
  NFS: Remove unused argument from nfs_find_best_sec()
  NFS: Eliminate duplicate call to nfs_mark_request_dirty
  NFS: Remove dead code from nfs_fs_mount()
