Log: MFC: r336215 Ignore the cookie verifier for NFSv4.1 when the cookie is 0. RFC5661 states that the cookie verifier should be 0 when the cookie is 0. However, the wording is somewhat unclear and a recent discussion on the [email protected] mailing list indicated that the NFSv4 server should ignore the cookie verifier's value when the dirctory offset cookie is 0. This patch deletes the check for this that would return NFSERR_BAD_COOKIE when the verifier was not 0. This was found during testing of the ESXi client against the NFSv4.1 server.
