commit 0b26a0bf6ff398185546432420bb772bcfdf8d94

    NFS: Ensure we return the dirent->d_type when it is known
    
    Store the dirent->d_type in the struct nfs_cache_array_entry so that we
    can use it in getdents() calls.
    
    This fixes a regression with the new readdir code.

    NFS: Correct the array bound calculation in nfs_readdir_add_to_array
    
    It looks as if the array size calculation in MAX_READDIR_ARRAY does not
    take the alignment of struct nfs_cache_array_entry into account.

    NFS: Don't ignore errors from nfs_do_filldir()
    
    We should ignore the errors from the filldir callback, and just interpret
    them as meaning we should exit, however we should definitely pass back
    ENOMEM errors.

    NFS: Fix the error handling in "uncached_readdir()"
    
    Currently, uncached_readdir() is broken because if fails to handle
    the results from nfs_readdir_xdr_to_array() correctly.

    NFS: Fix a page leak in nfs_do_filldir()
    
    nfs_do_filldir() must always free desc->page when it is done, otherwise
    we end up leaking the page.
    
    Also remove unused variable 'dentry'.

    NFS: Buffer overflow in ->decode_dirent() should not be fatal
    
    Overflowing the buffer in the readdir ->decode_dirent() should not lead to
    a fatal error, but rather to an attempt to reread the record in question.

commit b47d19de2c714020ba8f5545a6e7d4968f37eb45
Author: Arun Bharadwaj <arun@linux.vnet.ibm.com>
Date:   Thu Nov 18 10:36:43 2010 +0000

    Pure nfs client performance using odirect.
    
    When an application opens a file with O_DIRECT flag, if the size of
    the data that is written is equal to wsize, the client sends a
    WRITE RPC with stable flag set to UNSTABLE followed by a single
    COMMIT RPC rather than sending a single WRITE RPC with the stable
    flag set to FILE_SYNC. This a bug.
    
    Patch to fix this.

    SUNRPC: Fix an infinite loop in call_refresh/call_refreshresult
    
    If the rpcauth_refreshcred() call returns an error other than
    EACCES, ENOMEM or ETIMEDOUT, we currently end up looping forever
    between call_refresh and call_refreshresult.
    
    The correct thing to do here is to exit on all errors except
    EAGAIN and ETIMEDOUT, for which case we retry 3 times, then
    return EACCES.
