-stable review patch. If anyone has any objections, please let us know. ------------------ From: Steve French [CIFS] Fix oops when Windows server sent bad domain name null terminator Fixes RedHat bug 211672 Windows sends one byte (instead of two) of null to terminate final Unicode string (domain name) in session setup response in some cases - this caused cifs to misalign some informational strings (making it hard to convert from UCS16 to UTF8).
