commit a75b9df9d3bfc3cd1083974c045ae31ce5f3434f
Author: Trond Myklebust <Trond.Myklebust@netapp.com>
Date:   Wed May 11 18:00:51 2011 -0400

    NFSv4.1: Ensure that layoutget uses the correct gfp modes
    
    Currently, writebacks may end up recursing back into the filesystem due to
    GFP_KERNEL direct reclaims in the pnfs subsystem.

commit a8a4ae3a899a6c0b4771cc57884800d8b76a6996
Author: Andy Adamson <andros@netapp.com>
Date:   Tue May 3 13:43:03 2011 -0400

    NFSv41: Resend on NFS4ERR_RETRY_UNCACHED_REP
    
    Free the slot and resend the RPC with new session <slot#,seq#>.
    
    For nfs4_async_handle_error, return -EAGAIN and set the task->tk_status to 0
    to restart the async rpc in the rpc_restart_call_prepare state which resets
    the slot.
    
    For nfs4_handle_exception, retrying a call that uses nfs4_call_sync will
    reset the slot via nfs41_call_sync_prepare.
    
    For open/close/lock/locku/delegreturn/layoutcommit/unlink/rename/write
    cachethis is true, so these operations will not trigger an
    NFS4ERR_RETRY_UNCACHED_REP.
