Version 1.50
------------
Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
done with "serverino" mount option). Add support for POSIX Unlink
(helps with certain sharing violation cases when server such as
Samba supports newer POSIX CIFS Protocol Extensions).

note that it also requires setting CIFSMaxBufSize at module install

the list of superblocks to set these. Also need to check the

* Since cifs is a network file system, an "fsid" must be included for
* any nfs exports file entries which refer to cifs paths. In addition
* the cifs mount must be mounted with the "serverino" option (ie use stable
* server inode numbers instead of locally generated temporary ones).
* Although cifs inodes do not use generation numbers (have generation number
* of zero) - the inode number alone should be good enough for simple cases
* in which users want to export cifs shares with NFS. The decode and encode
* could be improved by using a new routine which expects 64 bit inode numbers
* instead of the default 32 bit routines in fs/exportfs
