Merge tag 'nfs-for-3.10-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client bugfixes and cleanups from Trond Myklebust:

 - NLM: stable fix for NFSv2/v3 blocking locks

 - NFSv4.x: stable fixes for the delegation recall error handling code

 - NFSv4.x: Security flavour negotiation fixes and cleanups by Chuck
   Lever

 - SUNRPC: A number of RPCSEC_GSS fixes and cleanups also from Chuck

 - NFSv4.x assorted state management and reboot recovery bugfixes

 - NFSv4.1: In cases where we have already looked up a file, and hold a
   valid filehandle, use the new open-by-filehandle operation instead of
   opening by name.

 - Allow the NFSv4.1 callback thread to freeze

 - NFSv4.x: ensure that file unlock waits for readahead to complete

 - NFSv4.1: ensure that the RPC layer doesn't override the NFS session
   table size negotiation by limiting the number of slots.

 - NFSv4.x: Fix SETATTR spec compatibility issues

* tag 'nfs-for-3.10-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (67 commits)
  NFSv4: Warn once about servers that incorrectly apply open mode to setattr
  NFSv4: Servers should only check SETATTR stateid open mode on size change
  NFSv4: Don't recheck permissions on open in case of recovery cached open
  NFSv4.1: Don't do a delegated open for NFS4_OPEN_CLAIM_DELEG_CUR_FH modes
  NFSv4.1: Use the more efficient open_noattr call for open-by-filehandle
  NFS: Retry SETCLIENTID with AUTH_SYS instead of AUTH_NONE
  NFSv4: Ensure that we clear the NFS_OPEN_STATE flag when appropriate
  LOCKD: Ensure that nlmclnt_block resets block->b_status after a server reboot
  NFSv4: Ensure the LOCK call cannot use the delegation stateid
  NFSv4: Use the open stateid if the delegation has the wrong mode
  nfs: Send atime and mtime as a 64bit value
  NFSv4: Record the OPEN create mode used in the nfs4_opendata structure
  NFSv4.1: Set the RPC_CLNT_CREATE_INFINITE_SLOTS flag for NFSv4.1 transports
  SUNRPC: Allow rpc_create() to request that TCP slots be unlimited
  SUNRPC: Fix a livelock problem in the xprt->backlog queue
  NFSv4: Fix handling of revoked delegations by setattr
  NFSv4 release the sequence id in the return on close case
  nfs: remove unnecessary check for NULL inode->i_flock from nfs_delegation_claim_locks
  NFS: Ensure that NFS file unlock waits for readahead to complete
  NFS: Add functionality to allow waiting on all outstanding reads to complete
