    [PATCH] knfsd: fix return value for writes to some files in 'nfsd' 
    Most files in the 'nfsd' filesystem are transactional.  When you write, a
    reply is generated that can be read back only on the same 'file'.
    If the reply has zero length, the 'write' will incorrectly return a value of
    '0' instead of the length that was written.  This causes 'rpc.nfsd' to give 
    annoying warning.
    This patch fixes the test.
