the following small patch should make it possible.

the vfs_init functions gets vfs_handle

and the module can have a DLIST witch cantains the following struct
struct {
         unsigned cnum;
         struct smb_vfs_handle_struct  *handle;
}

vfs_handle->conn->cnum contains a unique connection number with this as key 
we can find the pointer to the vfs_handle used for the current connection.
