[PATCH] knfsd: fix return value for writes to some files in 'nfsd' filesystem
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 an annoying warning. This patch fixes the test.
