commit ebcd6de98754d9b6a5f89d7835864b1c365d432f upstream.
Mounts to Azure cause an unneeded warning message in dmesg "CIFS: VFS: parse_server_interfaces: incomplete interface info"
Azure rounds up the size (by 8 additional bytes, to a 16 byte boundary) of the structure returned on the query of the server interfaces at mount time. This is permissible even though different than other servers so do not log a warning if query network interfaces response is only rounded up by 8 bytes or fewer.
