Re: [linux-cifs-client] [PATCH] cifs: fix oops on mount when CONFIG_CIFS_DFS_UPCALL is enabled

[Steve French]

I have not tried this code path recently and mount.cifs should always
be filling in the data field (with at least one mount option) but in a
case where the mount helper is missing, and the UNC name is of the
form //ip_address_of_server/share_name then I would prefer that we
treat this case (no mount options specified) as:
1) userid is \0 (null user)
2) null password
3) server id address comes from the beginning of the UNC name
(required or we fail)
The rest of the parms are at their defaults:
e.g. sec=ntlm  (for smb2 this will be ntlmv2, and perhaps we should
change the default for cifs as well)
