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@...ux.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.
